Better MC [FORGE] BMC4

[Stability Update]

Small bugfix update, fixing a few crashes in various mods. 

Moog's Nether Structures also got a major update, which added the Mega Fortress - A massive new nether fortress made up of 207 pieces and packed with loot, mobs and traps. It's best structure yet across all of Moogs' structure mods!
