This glitch keeps happening to me where... around wave 7 or so my vanguard can't decide whether she should be on the ground or one foot above where she is.... she just fluctuates between the two, and then it gets worse from there. It gets to the point where about wave ten-extraction I'm either stuck with an altitude of 5000 ft, or just start falling and falling and falling reminiscent of Bill and Teds Bogus journey.
I thought it was just me until I saw it happening to someone else... they just kept going up up and then away.
I hate having to leave that late in the game... I've already put that much time into it.
How prevalent is this issue? At least one out of ten games for me.
Another one I've come across to a lesser degree is when none of my powers work.. can only shoot... but nothing takes damage. Then you run out of ammo... but the box won't give it up. So you must quit.
