This does not occur with Buildcraft 2.2.14 + Forge 3.3.8.152 + ABO 0.9.1, no other mods

nor with Forge 3.4.9.171 (last 1.2.5) nor 3.3.8.164. Some other conflict?

Occurs with Optifine_1.2.5_HD_S_C6, BC+ABO, and Forge 3.3.4.9.171.
Optifine C6 is meant for Forge 164. But interestingly, this appears to be a load order problem. If I load Forge after Optifine, the problem does not occur, with 164 or 171.

Fixed by loading Optifine first

… but that causes other issues (water doesn't animate, Video Settings > Advanced OpenGL crashes NoSuchMethodError)

Ended up removing ABO in ExpHC 1.2.5rev5 since I couldn't fix this, ah well.

don't know whats causing that issue in abo. im dont using anything non standard.
