Garry's Mod Playermodel Weight Painting/Rigging Issue - Animation

Hello everyone, I’ve been working on a Garry’s Mod playermodel with Blender 2.81. For some reason, the weight painting on both the forearms and feet aren’t registering correctly when I compile it in Crowbar. I’m thinking it might be that the bones in the forearm and feet are not aligned properly, because I’ve made sure to thoroughly check that none of the vertices are painted to other places. I would appreciate any assistance on this matter.
