Hey,
so I build a personal claim a few days ago.
I wanted to decrease the claimed area.
When I clicked on remove claim on a tile I was expecting that I get a similar selection window to "add claim" where I can select some tiles that will be removed from the claim. However, instead the whole personal claim got removed.
Before that I confirmed a warning that said that that area will now be vulnable to anyone and that buildings on it will start decaying.
Instead of starting to decaying all my barkboxes with all my stuff disappeared instantly.
I did not loose much to it but still it was very frustating. I would suggest making this more clear so that other new players don't run into this.
