Wemod on payday 2 with other mods installed doesnt work?
That is correct, WeMod will not work with other mods installed.
isn’t there any way to make it compatible with mods? at least with mods that don’t have overlapping effects or commands?
As stated above, trainers will not work on this game if you have any other mods installed. This is likely due to how the game has been coded by its developers, which WeMod has no control over.
