When I load the gun, it only shows motion and it doesn't load. If I load it twice, the gun loaded, but it fire only one shot regardless of the magazine. Even it is weapon system 2! For example, I try load my colt python once, it didn't loaded. It still remain 0|6. And I reload once more, gun loaded looks success but If i fire my gun, It just fired once and left ammo just gone.
Im using Custom NPC mod and worldedit.

[ ] I reproduced this issue with as few other mods as possible installed.
[ V] I am unable to reproduce this issue consistently.
