-fixed Gearbox NPCs not having the correct material search paths

- Updated the MTB Extra Standup models because apparently I was using old ones somehow
(Not sure if the c4a2a Gonarch intro model works? I tried just starting the chapter and then completing the map before and nothing was different. Also tested the apprehension model and it also did not do anything. Unsure why they were included but I'll include them none the less)

- Fixed MP5 muzzlefash being inside the barrel

- Fixed Satchels disappearing during running

+ Small Alternate options Update
