"This server is using a modified assembly." Been like this for two days for me, only really play on these servers.
Those who can not join need to post their steam64ID. Nelson's upgrade to allow rotation of items in hands/tops/vests/bottoms has corrupted player folders on individual servers. It will need resetting for each person. You will lose your inventory and XP. Bits will remain as that data is stored separately. Cory, the server owner, may need to do the individual resets.
