Hey everyone, I'm here posting to try and learn from whatever I did wrong. I had a claim on an island that was entirely walled off, and a guy had been harassing me for a while around there. He had never managed to get in my walls, and he never got a hold of any master keys or whatnot. I logged in earlier to find all my stuff and my hearths still exactly where I left them, but my claim was now entirely his claim. Nothing changed, except that the claim is now his. The only thing that comes to mind is maybe he picked all my locks, destroyed my claim, and then placed his own over it in less than 12 hours.
Any ideas? Pretty amusing to be honest, he got me good - just don't want to have it happen again.
