I have tried this on 2 machines, each resulting in the same crash. As soon as a weapon is fired by anyone other than the host the game crashes with the following error on the user's (client's) side.

java.lang.itemindexoutofboundsexception

Then returns to the home screen

Use pastebin please...

Hi, I've been having this same problem.

Mod version: 1.2.8-1.19
Forge version: 1.19.41.1.0

Like ironslaves reported, firing bullets kicks at least one person off a LAN server and they get the "java.lang.itemindexoutofboundsexception" error. The game itself does not crash so no crash log.

i am having this problem too!!!

whenever i fire a gun more than just for a single shot, sometime a single shot

i am having this problem as well ! super annoying

whenever i fire a gun more than just for a single shot, sometime a single shot
