Recently text has been disappearing, is has been happening to me when i installed this texture add on. I can restart ftb and it will fix it but it happens every 10-20 min. I tried to update my java 32x and 64x to fix it with no change. My specs are FTB 1.0.1, Core i5 4.4ghz, AMD 7750, I have 16 gigs of ram and I am feeding 8 gigs of ram to it. I am using 256x reg and 128x mod. I'm using this pack "http://bdcraft.net/forum/128x64x-feed-beast-beta-pack-texture-pack-add"
