Most likely, the problem is not in this mod but in your OTHER mods. This is usual mod conflict. Unfortunately, the times have come when young hot blear-eyed modders pushed into their mods everything (files from physics, trucks, weather, textures, anims, etc.). So in every your mod could be some parts from Magnum, аnd you must manually check each of your mod.
The first thing you had to do is to upload your gamelog anywhere and share the link here (because all telepaths are now on vacation).
Also you can try to set highest priority for Magnum mod in your mod-manager - and see what happens...
