Thread title pretty much says it, when I enter a certain area of my SMP map all the modded blocks suddenly disappear as if they are missing a texture (eg ores that aren't standard) and you can see through them (and walls if there is a block behind them). I have RP and BC installed and their blocks also do the same thing, I doubt it is due to IC2 alone but I figured I would post just in case someone knew why this was happening. I also have Optifine installed, any ideas?
