One note, one comparison

Check what a patch actually changes

Record the installed version, the exact announcement line, the action you expected, and what happened instead. Start with one affected system.

Make a short comparison record

  1. Open the matching official announcement through Version Notes. Match platform and installed version.
  2. Copy the specific changed rule. If the note does not mention the system, label a patch explanation as a hypothesis.
  3. Record your item, talent, route or machine state and one repeatable action.
  4. Compare one change while keeping the rest stable. A different world, difficulty, mod list or boss is a different comparison.
  5. Use the direct guide when the failure is a known access, recipe or attack mechanic. Stop expanding the patch investigation once the task is identified.

Examples tied to specific announcements

Drills or traps stopped damaging targets

Version 1.3.0.4 fixed drills, spike traps and some other hazards not dealing damage. 1.3.0.4 hotfix.

Check the installed version and one simple powered drill before rebuilding a factory. Slow output with working damage may instead be orientation, depletion or collection.

Drill diagnosis

An old marker or travel timer no longer matches

Version 1.3.0.1 expanded map marker customization and reduced Waypoint and Portal activation time. 1.3.0.1 update.

Read the current marker controls and activation state. Test one return destination rather than reusing an old fixed timer.

Map comparison

A summoning or Magic setup changed

Version 1.3.0.1 changed persistent minions and Magic talents. The release notes apply to that update, not every later build problem. 1.3.0.1 update.

Record the current tome or staff, talents and active effects. Compare the same encounter before attributing a difference to a damage nerf.

Build comparison

Separate versions, mods and guide revisions

For a modded save, make a backup and use the mod conflict workflow. For shared worlds, confirm the same build and ownership through co-op setup.

A review date on this site records an article review. It does not establish when a game mechanic changed. Use Latest Guide Changes for article revisions and Updates to choose a specific save comparison.
