Midshipman, Engineering Corps
1. Go into a multiplayer match (did not test if this bug also occurred in SP)
2. Select a building to place
3. Notice you can only move buildings vertically
4. Find a place where the building is white i.e. you can place it there, but is at least one tile above the ground
5. Press Ready
The building is automatically moved to the nearest surface as buildings cannot float in mid-air.
The building falls down and collapses almost entirely.
Yep, verified, thank you! Looks like the multiplayer setup isn't properly finding the y-position of buildings. Will get fixed in v7.2.
