If you jump in multiplayer (it doesn`t happen in singleplayer) on a slimeblock which has a flowerpot ontop with a cobweb above and hit the flowerpot the server crashes. In the serverlist the server is shown online, with the crash-causing Player being online, but it is unjoinable (Read:timeout). I attached the setup and the serverlog.
Does this error still occur in 14w03b? (or the newest snapshot if there is a new one)
The log is from 14w03a.
