Just logged in pve9 in my base, noticed a bridge of wood siding goes up my base, but the server disconnected. The raider was only able to get one of the six lockers in my base and that's why i am suspecting he might still be in my base. Currently sitting in base with group member hoping to catch the theif the moment he logs in. (Finalestage is group member)
I'd place new roof panels and extend and move the base, then salvage the area where you think the griefer may be... Basically a relocation. Let him fall. XD If you managed to get a name we can look for him.
The thing is, I turn almost everything I don't use into points the moment I get them. So raiders cant get anything from raiding my base. I just hate them destorying beds and my base is pretty high up.
All the more reason to move a few squares one way or the other, or if he's in the middle of a panel, wall him in and let him die.
