A post was merged into an existing topic: Error from moving things?

Both errors seem to be related to building. Did you possibly see these errors earlier when working on a custom building? Sometimes the errors appear on every load as the game looks at what is in the save…

I cant remember specifically what i was doing when they started popping up, they did continue to show for a while when nothing is building but they stopped. Ill upload the save incase you wanna take a look, ive had some new errors since then.
