I can only find a small part in the xml files as part of each weapon:

<supportedArmors>
<li>VWE_Apparel_Exoframe</li>
</supportedArmors>
<supportedTraits>
<li>Tough</li>
</supportedTraits>

Seems to indicate only the exoframe supports heavy weapons, even though the mod description says any power armor should support heavy weapons, but I also barely have any understanding of these mods, given I never made or edited one. I don't even understand why there's no 1.3 file in the Mods\Vanilla Weapons Expanded - Heavy Weapons directory.

And besides, I can't even get the mod to work, no matter what combination of mods I use. To me the weapons cannot be picked up even if a colonists is wearing cataphract armor, exoframe and has the tough trait. Only incapable of violence colonists give the option to equip them, except the option is disabled because they are incapable of violence.

I honestly kind of think this mod is discontinued and broken, but then again, I could be wrong and just didn't try hard and long enough.

ever figure out to fix the issue?
