currently investigating. Appears there is a crash when creating a new camp aswell. Which was not present before merging - perhaps recent panels PR changed editmap.cpp somehow, cant see how though, but will dig further.

Ok I changed the logic in updating the camp after overseer resigns, should fix it, some weirdness , including a crash was caused by editmap() being affected by the recent panels UI PR changes. So I think that fixes both of these problems.
