I've never gotten it.
Guns that don't work (Idk if this is just on my side or not )
They were all mountables. Sorry!
All of the guns seem to be working fine on my side as well gboto. Ill continue looking.
I'm getting the same problem as someone here said with bombs and the like. But not guns. So idk.
Edit2: It's working now. WTH? It seems to have fxed itself... I don't know what to tell people. Just log out then log back in maybe?
I had installed Optifine and TMI since they're popular mods and crafted the guns manually as well as spawning them in.
I'll take a look at bombs since I've never played with those and see if it crashes.
