Windows .exe Direwolf 20 1.0.12 game breaker

[bossesdream]

This version of the modpack has deleted my world.dat_old on 3 separate occasions. One world was about 12 hours of gameplay, then under 8, then this latest one i just started today. I don't know what causes this, but i don't think i can recreate this doing the exact same things. The only thing in common with these worlds are the smelter and portal guns.


The crash report: http://pastebin.com/AmNP1n1A

p.s. this is very frustrating

Update the pack to 1.0.14 it is a problem with the hats mod. Don't use an exisitng world create a new one. If you never use the hats mod you could always disable it.
