Update before troubleshooting
An official launch-week hotfix specifically mentioned the mission “A Roof Against the Wind.” Close the game, update Steam, and compare your build before changing the save.
Read the current objective text exactly. A pre-release video or demo guide may show a trigger that no longer applies.
Verify the trigger
Record the structure placed, its completion state, location, objective text before and after placement, and whether the host or a co-op guest performed the action.
If the build predates the patch, test a fresh save only as a comparison. Keep the original save and wait for official guidance if progress remains blocked.
Avoid false certainty
This page does not publish an exact building count because the current objective must be confirmed in the live build. Add a tested value only after two independent checks or an official note.
