Im not sure if its a bug, but it looks like.
My gf wanted to place a claim at the gate of a cave, in the inside I mean. I went there first, builded a pallisade and blocked the entrance. Then I placed a dream or a stone, I'm not very sure about this, and I left. My gf went there, placed the other items and builded it.
I wasnt wearing my bound in my inventary, and that was the first claim of my gf. A bound apeared in her study but she told me that it was impossible for her to click the idol. I logged in her account in my computer and I tried with her char, but I couldnt click it. It was like bugged, but I thought It was something about the new patch and forget about it until today(that was yesterday).
So Ive headed to the claim to check it and I've discovered that the claim was mine. So the claim was build enterely by my gf following the heartfire building: i place the dream, she finisihes it and it becames hers. But in this case it became mine, and the bound went to her study box. She placed it in the cupboard and there is a -720/720 or something like this on it. Ive just declaimed it.
