It's what the topic title says. I'm having my test mod above every other esp in the load list and i've realised through trying to make it work that fwe overrides it even though it is much further in the load order. W/o fwe everything works fine (custom and edited weapons etc) even with a plethora of other weapon mods.
Did my research but came up with nothing.

Thanks in advance

You have it at the top? Of course everything is overriding it. Put your mod at the bottom, that way it overrides everything else.

Jesus, i'm stupid, thanks
