If Phase 3 wrecked your factory in an older build, the damage came from a scripted falling-object event documented in playthroughs and acknowledged by the developer. A Steam announcement says that event was removed on August 20, 2026, so it should not be presented as inevitable current behavior. Update the game first; if an older save still contains debris, stop production, clear the route, and rebuild only the damaged section.
Check the game version before rebuilding
The most important distinction is between the old scripted event and the patched current build. Videos recorded the Phase 3 transition dropping large objects into established production lines, but the developer later announced that the event had been removed. Update through Steam and relaunch before assuming that a fresh Phase 3 transition will repeat the destruction.
Recover an already affected save
An update cannot automatically prove that every object in an older physics save has returned to its previous position. Turn off the affected tools, remove debris from intakes and narrow channels, and recover any products or panels trapped under the fallen objects. Restart the shortest production loop first, observe several cycles, and only then reconnect more complex branches.
Rebuild for visibility, not for the removed event
A cleaner layout still helps normal physics troubleshooting even though the scripted event is gone. Keep critical junctions reachable, avoid hiding the only intake behind stacked panels, and leave enough space to stop and clear a jam. These are recovery and maintainability practices, not claims that the current game will trigger another Phase 3 collapse.
Separate a legacy event from an ordinary jam
If the game is current and no falling-object transition occurred, inspect the line like a normal automation problem. Check for products thrown by stronger fans, items wedged against bumpers, loose panels, or a crowded collection zone. Calling every post-Phase-3 failure the removed event would ignore the developer fix and can send players toward unnecessary full rebuilds.
What to report if it happens again
Record the game version, save age, platform, exact phase transition, and whether large objects visibly fell before the line broke. A current-build reproduction would be new evidence and should be compared with the August 20 announcement rather than assumed to be the same bug. Until that reproduction exists, the accepted conclusion remains that the scripted destructive event was removed.
