Memory leak in arena's?

[Ebel]

Sometimes after playing some pvp matches in the arena my performance is going down at the point my opponent hasnt even loaded his model yet or getting below 20 FPS, whats up with this? 

This happend now for the 3rd time after like playing 1hour straight of doing arena's, this never happens in open world anyone else got this problem aswell? oh and im from EU if that helps.

I think yes, I played about 70 arenas, and then my fps dropped from 60 to 8 fps. I had to rr the game tto fix it.
