lots of bugs together in one round

[TheWarwick]

I played a round and i had fps drops from 60 to 20 in every single fight I couldn't summon my archwing and hoverboard most of the time, but from time to time after a meele attack i could summon the archwing. By the excavator mission when i picked up a energy core while reloading the weapon wasn't changed to secondary (it stayed by main weapon(arca plasmor). And in the whole round i didn't had any description of my objective or how far we were. Also while traveling with the archwing the position of the objective sometimes jumps somewhere else and after flying further to my allies on the true objective point it changes back.
