If you have ever installed custom weapons and forgot to sell them before removing, chances are you now have a broken save file, leaving you unable to open the game. This mod attempts to fix that.
REMOVE ALL OTHER MODS FIRST. This includes Beardlib. This should go without saying, but apparently not.
Mod should be removed after use. Ideally, you should install this mod, start the game, exit the game, then remove the mod again. Nothing terrible happens if you forget to remove it, but you might run into some minor issues. This mod does not clear your inventory, so don't worry about that.
To install, extract the zip file into PAYDAY 2/mods. You must have the BLT Hook installed. To uninstall, simply remove the CustomWeaponCrashFix folder again.
