As soon as the structure is fully removed after “Remove” command this error appears.

Searching the forum saw other “attempt to call” bugs but not this particular variant so it seemed like it should be a separate thread, please merge if I’m incorrect.

I’ve got a similar sounding error message when removing a partially build building that refused to be finished. After closing the message it got removed alright.
