So I managed to install and run openxcomextended on pop_os! and I was looking forward to get my favourite mod (x-com files) up and running. I installed it into the mod folder and went to activate it in game, but I get the error message:
ERROR: failed to load "X-Com Files"; mod disabled
Weapon STR_HUMAN_SONIC_SHOTGUN has a clip size 0 and no ammo defined. Please use "clipSize: -1" for unlimited ammo, or allocate a compatibleAmmo item.
Does anyone know how I can solve this issue and get stuck in killing fish-faced cultists?
