I got the same problem!
It does not have anything to do with the color.. Its the 1.3.1 release.. Craftbukkit, or Minecraft itself..
Well yeah, i use SimplePrefix. It works sometimes. When spamming TAB.
I always used TAB to fill in playernames when typing in chat. But now it seems like it does not work at times. Is this function been removed, or...
I get No Sources Available on every plugin i have installed.. worked fine with some plugins before..
Separate names with a comma.
