I keep getting crashes on our server when loading new chunks. They sometimes become corrupt and cannot reload that chunk. It is odd, because we can load a lot of chunks and randomly we run into one that crashes the server. If I log back in, and go back away from that chunk, it is fine again. Until I load another random chunk it doesn't like. I am running MC 1.7.10 with JAS 0.17.2, and 43 other mods on Forge version "forge-1.7.10-10.13.2.1346". I will paste the crash log below -
