WE FOUND A FIX FOR THE TIMEOUT LOST CONNECTION PROBLEM!
Our server owner got the hint to deactive the "rawsocket" option (thanks to LeoCom @ Ark Game Server Owners Discord!) and now they seem to reboot properly. Mods are loading as well.
We assume it's due to the last patch affecting feeding troughs.
When we pick up the trough, the visual border disappears. As soon as we place it down again, it reappears. ?
