Tribe invite bug takes over private base

[TouchStone]

I have a tribe and I'm a admin of the tribe. I had a random noob run up to me at my base trying to get in then he sends a tribe invite to be while I was killing him.... I hit e to loot the body... it put me In his tribe. I just noticed it.. left the tribe now my metal base that I own is under his tribes ownership and I'm locked out. Even tho it says I'm the personal owner... this base took me and my tribe mate a week plus to build and I'm locked out. Plz help. This is a dangrous bug or glitch and needs to be addressed.
