your blocks, they are just troublemakers
Wow! XD And ouch. What happens if you save as a template and move the castle elsewhere on the map? I suspect it’s having trouble with sitting on top of whatever underground structure you have right underneath.
Also we did recently change some building code. If you have a save, please upload for @not_owen_wilson to take a look at.
The issue was that they weren’t connected. I rebuilt both of the parts seperatly and it worked fine.
No save file, sorry
Yeah, weird stuff happens if the buildings intersect terrain too much, even if it’s accidental–ie, they both think they’re part of the same building project. GLad it worked separately though!
