World Won't Load

[BluntlyJess]

Since the latest update, I have been having problems getting my world to load on Attack of the B Team. Any suggestions to help fix it? I already reinstalled both technic and the mod pack itself multiple times, setting it in beta instead of the stable build, deleted my resource pack (it was causing issues anyway), uped my java memory (at 4gb) but it still doesn't load my world. Everything is blank like the chunks aren't loading but everywhere not just one little location like normal chunk loading errors. I can see the sun when its day, the moon at night, and clouds, but no ground. Please help
