http://jenkins.minecraftforge.net:7070/job/forge/213/ Grab #213 http://calclavia.com/icbm/?page=downloads Grab ICBM v0.5.1 http://www.minecraftforge.net/forum/index.php/topic,61.0.html Grab UE 0.5.1 Put UE & ICBM in the mods folder and Forge in the .jar By the way, this only happens on a server so DL and install those onto a quick server and join, then basically rapidly break/place blocks and jump around, I find that going into creative and flying is what usually trips it.
