Only fix I found for rotarycraft so far was copy the new textures from updated rotarycraft jar to resource pack used. That fixed all my problems with the silver flakes and upgrades.
The crash w/BOP is fixed now with stealth update of 0.5.9.2

- Hope they update Binnie Extra Bees/Trees to ver 1.7.1 too.
