Ok so i get straight to it, if you (WThieves) and some others of you remember, i made the KATFYR Pack, wich worked fine in 1.6.4. Now, as i tried it in 1.7.10, and did rename the IDs to NameIDs like 266 to minecraft=gold_ingot, the client atleast started up. However, as i try to put the gun into my inventory, i get this crashlog:
Also by looking over the code i see galacticraft in this, however it cant be, simply cause of ALL other guns work, i mean all of the ones included in the mod and external ones like the mario one. So ye it can only be my gun, just that i dont know whats wrong, if needed just tell me and i will upload my gun pack here.
Thanks in advance. Regards -Yanniclord
