Bugs?

The game is really full of bugs.

It happens very often that my chars i  online career get stats i never use and complete stuff i never do. 

For example i can get stars in something ground relate but we where never on the ground. I get wins for submisions but i was never on ground and they got knocked out. In my stats it says i have won by submisions 137 Times but i know for a fact the real nr is 2. 

And im pretty sure double xp dont work sometimes. Like 2day i played almost 2 hours and got match after match  with  o downtime and only got 75 eveloution points i  total?
