- Weapons parts moving "alone". Ex: Rifle's bolt moving without the character's hand grabbing it.
- Animations messed up. Ex: MX 3GL, rifle's bolt get to the rear when reloading the grenade launcher.
- Weapons drill are wrong. Ex: Reloading on a not empty mag, you should just remove the mag, and put another one in. No need to arm, and/or use the bolt stop.
Everything is explained in this short video I made: http://youtu.be/_cH7uQ4cl1U
