Help! I was playing normally and went to visit allengero's shop at 19000 on SMP9. Suddenly the game completely locked up, something it has never for me done before.I used task manager on my computer to close out Minecraft and then reopened it. The game runs fine on single player and on other multiplayer servers but every time I try to connect to Empire Minecraft I get a pre-render error (GL Error 1281) and Minecraft completely locks up on me again.I'm stuck at 19000! What can I do to rectify this? Thanks! Edited: Never mind. It seem to be working normally now. Weird. Thanks anyway.
