Valheim World Modifier Change Log Worksheet

Why a dated change log beats a remembered decision

Groups usually change world modifiers for a reason they can state at the time: the iron runs are eating the whole session, the raids keep interrupting building, the corpse runs are wearing people down. That reason is clear on the day and gone a month later. What survives is the setting itself, and a setting with no history looks like it was always there.

A dated entry fixes that by attaching four things to each change: when it happened, what the value was before, what it became, and what the next session actually looked like. The last field is the one most people skip, and it is the one that makes the log useful. Without it, the log records intentions. With it, the log records outcomes.

Iron Gate's support page routes bug reports and feedback to dedicated forms and keeps a known-issues list, and it also hosts help articles on topics such as developer mode and dedicated servers. That means the reporting channel already exists. What is usually missing is a comparable record of what your group changed and when. A short, dated log is easier to line up against a known issue than a paragraph of frustration, and it is easier for a second player to confirm or contradict.

Keep the log small. A form with twenty fields will not be filled in consistently; one with six will. The point is not to capture everything that happened. The point is to capture the same thing twice, in the same shape, so two entries can be compared.

The entry shape and what each field asks

The table inserted after this section is a synthetic example of the worksheet shape, not a record of a real session. It shows six rows and three cases, which is simply the number of times you repeat the observation. Nothing in it is a product specification or a field test result.

The first field is the entry date. Write the date you made the change, not the date you wrote the log. If you are reconstructing an older change, write the date you believe it happened and mark it as approximate rather than presenting a guess as a record.

The second field is the setting category you changed. Record the category in your own words, using whatever label your session presents, and do not invent a category name you did not see. If you cannot recall which category it was, write UNKNOWN and say where you looked.

The third and fourth fields are the value before and the value after. These are the two entries most often quoted from memory and most often wrong. Read them from your own session's display and copy them exactly, including any wording your session uses. If you did not record the prior value at the time, write UNKNOWN rather than reconstructing it from the new value.

The fifth field is who made the change. In a shared world this matters more than it looks, because a setting nobody remembers changing is usually a setting somebody else changed. Record the person, or record that the change was made by an unidentified member of the group.

The sixth field is one observation from the next session. Describe what you saw, in plain language, without naming a cause. "The first iron run finished with time left for building" is an observation. "The resource rate fixed the grind" is a conclusion, and it belongs in a separate note, clearly labelled as a theory.

Filling the before and after fields honestly

The prior value is the field that makes the whole log worth keeping, and it is the field most likely to be missing. If you are starting the log today, you have two options: record the current value as the baseline and mark the prior value UNKNOWN, or reconstruct the prior value only if you can point to something that shows it. A remembered value is worse than an honest blank, because it looks like evidence.

When you do record a change, write both values in the same session, before and after, without leaving the screen. A change recorded from memory the following day is a different kind of entry from one recorded at the moment, and the log should say which it is. A short marker such as "recorded at the time" or "recorded from memory" costs nothing and prevents a later reader from over-trusting the entry.

Do not treat the log as a place to argue about whether a change was a good idea. The log records what changed and what followed. The argument belongs elsewhere, and mixing it into the entry makes the record harder to compare against a second entry.

One more habit matters: keep the log in one place that the whole group can see, and note who is responsible for it. A log split across three private notes is not a log; it is three memories with extra steps. Iron Gate's official FAQ states that Iron Gate does not provide official servers and has no access to your saved worlds or characters, which is a useful boundary to keep in mind: your log is the only copy of your group's history that anyone outside the group can see.

Writing the observation so it can be compared

The observation field is where most logs fail, because it invites a verdict instead of a description. A verdict cannot be compared against anything. A description can.

Write the observation as something that could have happened differently. "We finished the first iron run with daylight left" is comparable: a later entry could say the opposite. "The setting is better now" is not comparable, because there is no version of the next session that would contradict it.

Keep the observation to one or two sentences and tie it to a specific session. If the group played three sessions after the change, pick the first one and say so. If nothing notable happened, write that nothing notable happened. An entry that says "no clear difference observed" is a real result and is often more useful than a vague positive one.

Separate the observation from the explanation. If you believe the change caused the result, write that belief in a clearly labelled note beside the entry, not inside the observation field. The reason is simple: the next entry may show the same result after a different change, and a log that already committed to a cause cannot show that.

Finally, do not change a setting just to fill a log entry. The log documents changes your group chose to make; it does not require you to make any. An empty log with a recorded baseline is a valid starting state.

Reading the log later without over-claiming

When you return to the log after several weeks, read it as a sequence of dated entries rather than a set of conclusions. The useful question is not "which setting was best" but "what did we change, in what order, and what did the next session look like each time."

Look for entries where two or more settings changed in the same session. Those entries cannot separate the effects, and the log should say so rather than implying one setting produced the result. If your group tends to change several things at once, note that pattern in the log itself, because it is the single most common reason a change log stops being useful.

Look also for entries where the observation is missing. A change with no recorded follow-up is an open question, not a settled one. Marking it as open is more honest than filling the gap later with a remembered impression.

If a later session contradicts an earlier observation, record the contradiction rather than editing the earlier entry. A log that has been quietly corrected to match the current view is no longer a record of what happened. The value of the log comes from the fact that it can disagree with itself.

This worksheet is version-neutral and does not assert that any setting produces any particular result. It is a documentation method, not an in-game verified fix, and no game build was installed or tested for this article.
