I just lost all of my items with the exception of my power armor and chain sword after having come back from a lengthy mission with a bag full of worthy upgrades.

I crash after completing missions 100% of the time but receive rewards upon logging back in. 

My character floats when using a melee weapon and pistol, and the mission I played with power hammer/pistol, the hammer had no animations

I've also had occasional problems with the assault jump ability, sometimes the character will jump straight up and back down but the damage effect will play where my cursor was. No damage will be done. I have also had the character walk all the way to where I indicated to jump then jump up and land. Damage will be done. I feel the ability triggers correctly 50-60% of the time. 

I also appeared to be floating when moving while using power sword and inferno pistol. 

No animations for any attacks either with pistol or with sword, however the rocket pack and the grenade both did have animations.
