When you try wearing other clothes the items turns to the same costume that you wear or disappear.
Having this issue as well. I cannot equip crafted clothing items.
Also, I don't know if it was just the server I was on, but sometimes local chat doesn't show up when I hit "enter." Maybe the server was just overloaded with too many local chats?
There still seems to be a bug on freebuild mode where players can't spawn or craft anything. Sometimes when I come on it works, but if I get disconnected and rejoin, I can no longer spawn or craft items. This bug was also present in 0.11 and it seems to be completely random.
This is not a mod problem. This has to do with a server turning Survival Mode off or on. When survival mode is OFF, you may craft and freebuild without resources, and when it is ON, you have to have resources and you have to survive.
