Another mod you're using is probably overwriting those weapons.
Nope, I checked your mod files; you forgot to add mjolnir.wpn and shredder.wpn (as well as mauler.wpn) to reassign the sound effects.
All three of those specific cases were reverted back to vanilla because the vanilla sounds were improved at some point. I kept the sounds in Audio Plus in case some mod wanted to use them.
I still believe the modded sounds are way better than vanilla.
I tried adding them in but... weird stuff happens. I've ripped the vanilla .wpn files and placed them in the appropriate audio plus directory. I've then edited those .wpn files to replace the sound references with those from the mod.
What happens is that, this works and replaces the sound, but now all of a sudden Mjolnir thinks it's got 4 barrels instead of two. While firing, it splits its two barrels down the middle and alternates animating the recoil of the half-pieces.
Same thing happens with Heavy Mauler, with it splitting its single barrel into two and alternating the two halves while firing.
I'm seriously baffled. I'm working with vanilla weapon files from the current version and I've literally didn't touch anything whatsoever except for the fire sound audio line.
