Metion Shotgun Category is now configurable in the .ini. By Default it is set to Rifle so with vanilla classes specialists, rangers and rookies can use it, but now you can change it to whatever you want to fit better with whichever class mod you're using.
Tried to fix the issue of the Proving Ground projects not appearing in an ongoing campaign, seems to work but i don't think it works if you have already researched the Custodian/Exalted Custodian Autopsies.

Forgot to rebuild the mod before uploading, metion battlesuit bug should be fixed now. Probably. Again.

Fixed a bug that made the Metion Battlesuit invisible... Probably.

Quick bugfix.
Mk2 Custodians can now fire their guns and use their melee attack while on fire.
