Mesh accessories are bugging out when I attach them to a rig

I have imported and organized my meshes from blender into accessories. I have done this exact process in the past without failure. However, now my meshes will stretch out/shrink/grow on the rig if there happens to be more than one accessory on the rig. I am currently working on a commission and this issue has caused many delays. Any help would be EXTREMELY appreciated.
