Im not sure why it does this but for some reason whenever my friend joins for him all of the world textures disappear. The mod works just fine in single player.

Please provide minecraft version and mod version, if possible also provide forge's version

everything is 1.8.2
Epic fight version is 18.1.13

Okay after some testing we found that optifine is what is conflicting with epic fight

Optifine issues are hard to fix for now. Since it's not an open source.
