Have same issue

I'm guessing it's the update to Gmod that messed something up.

I'm also getting errors with attachments while on my dedicated server. I tested it with Gunsmith Arms: Source and (almost) all the EFT addons and I am getting the same results of my attachments not working.

Might be the update for Gmod clashing or I gotta do some cleaning for my addon list. I might have a strong guess to the issue.

same issue on the server i frequent. 99% sure recent update borked it

Still getting this issue as well, even with the recent update to ARC9 on the 19th that attempted to fix it

I was able to fix the issue on my end, by removing a addon that added in skins for the M14 on the MWB base.

wierd fix but what is the addon?

It was removing a addon that gave me skins for the M14 on the Modern Warfare Base.

link?
