I was waiting for half a hour for someone to join. I gave up and left, looking for servers to join. I sorted the server list by players and my server which was still on the master server list appeared as FULL. I had set my max players to 99 before starting the server.
Upon starting a server again I saw that the max players that was set was blank. Anyone else encounter this bug?
EDIT: And how do I get my server off the list?! It's still there!
EDIT2: I blame System_GuiPlus!
EDIT3: I uninstalled GuiPlus and now my server's not on the list. I guess GuiPlus is the culprit. I tried to join the server which I had already shut down before uninstalling GuiPlus and it put me in Boss Battles instead.
EDIT4: Seeing as I've discovered the culprit of all of this I'll lock the thread.
