The new update allows you to evaporate weapons or ammunition from save files that were previously used.
If you don't want this, please download the old version.
There are many new Updates features that have been added and changed. Please take a look at the Gunfighter page for details.

If you see any bugs or problems in the mod, please write it down on the report page.
An error may occur when using the existing save, so it is recommended to play with a new game.

There may be a mod conflict when using the Ammo & Magazine icon MOD for build 41 mod and other silencer mods.

Not confirmed first hand, but ill have a look later.. in the mean time, if you cant see attachements, and run Canteen mod, try disabling it.
