Zombies Dale

Glitches i'm trying to fix --MAJOR-- Putting Grass/Wood Slabs in the furnace makes it explode with glass and Concrete Crafting not working Houses falling apart for no reason --MEDIUM-- Getting multiple items when crafting only a single item. Bombs cause lag. Processor will be floating. --BASIC-- A single chunk being missing. Map will sometimes be on top of the survival base. Map generation can cause lag for about IO sec.
