You can request for a mod compatibility here, I've known some mods to not be compatible like Mors Longa, since it has its own arm rigs (you can see like 4 arms lol).

Some mods may require me to get in contact with them, so please reply with these notes:
Mod Name: <name>
Steam Workshop: <link>
Author/Leader: <name/link>

If you don't do this, I may not be able to help you, anyways thanks!
