When we tried to load this mod any skin with a negative value like "-2095032307" for example will make the mod not load. Is this a bug or is there a way to get around this and ise the skin?

What is the link to this skin on the workshop? I don't think workshop skins should have a - in them

I dont have the link to them i have a dumpfile with the skins i got here

and there are some that start with -

you could try using the mod with the default config and adding those skins manually via commands to see if they're valid? for example "/skin add rifle.ak -2115580770"

If it throws an error/no skins appear for the ak then try it without the - , like kman said I'm pretty sure workshop items shouldn't have a - in their id.

Ok yeah I think they may be in error because after hours of looking I couldnt find anything that was a negitave value. still not sure why they are there but we removed them LOL
