First off, I've only been playing for about a month now, so I don't know exactly how important this may or may not be. I also didn't actually take a screenshot when we caught one of the thieves the second time.. This is kind of the first time doing much with the forum
Anyway, there was a thief that was trespassing around my small village of friends, but we never were able to get any evidence of him actually stealing anything, and had a few things unclaimed in our mine, which he ran off with. We were active enough however to get his scent and follow him back to his hearth fire and stash. On the walk there, we found out that the other small groups were raided by the same person, and felt a little bad for them. I went in and took back my stuff, and left.
The next day, there was more tracks of him wandering in our mine, but we fixed the claim problem. He didn't take anything. A couple hours later, I walked into the mine with him there, stealing from it again. I knocked him out, but let him live, if he never returned. He never said anything back and ran off.
I wasn't sure if he was just going to come back and try again, and I didn't want to kill him, dealing with any type of revenge from him.. So I walked back to his camp. When I got there, I found 3 dead characters, and 5 people in his crew. 3 of them had swords, and Necromancer's Cloaks, so I was a little worried of getting ganked and killed.. But, I saw they had been busy raiding everyone around them, having many more chests, and a wagon and ox. Based off of all the other tracks, I can only assume they are stealing everything around them, and won't stop until someone fixes this..
I saved the conversation I had when I went over there, and they didn't attack me, but did constantly try to send me back to my hearth fire - They were successful a few times as well.
They are located at (-36, -42) south west corner of it.
I don't know if anyone is willing to help with this.. But thank you ahead of time if you do!
