Hrm, no dice it appears. The problem seems to have been fixed all by itself. And just to clarify, it was an error, not a crash. And answering Ymus' question: it was all of the /scoreboard teams commands. I'm guessing that this was just some sort of 1 st - run bug of some sort. It's working normally now.
Huh, quite odd. Just like magic it's fixed. I'm not quite sure how to reproduce this problem, I think it may be the fact that I ran a server and played Mc at the same time. I'll attempt to recreate the problem tomorrow.
In this update I hate that you cant see you coordinates on the map, I want to use command blocks to teleport and i dont know where to teleport i cant get the location cause they removed it
