Existing structure not repairable

[Soesah]

I'm not sure it is a bug, but if you move in to an existing structure, and it gets attached and damaged, you cannot repair it. You can't deconstruct it either, so in the end, you end up having to rebuild it.

If you are talking about the ruins you can mine them to remove them, but yes you can't repair them. It's not a bug, it's a feature

I'll have to think about how to handle this.

I'll have to think about how to handle this.

I would love if there would be a way to "claim" old structures.
Maybe with an "examine" action by pawns with scientific background.

Later on that could be combined with an archaeological base camp for more complex recovery of other stuff besides some simple walls?

I'll probably just make them repair stuff in the home zone.
