Got a Fatal Error still continued playing, won the battly with 100% activity

First this is my first post here on reddit and English is not my first language.

​

So I just finished this absolutely insane RB match and I'm still confused as how this played out.

I was just playing my 5.7 German lineup when after about 2.5 minutes into the match I got a little pop-up "Fatal Error" the game crashed. I was confused because I could still see my plane moving and stuff, so I tried to continue playing... It actually worked I could still play even tho it had crashed. The graphics got worse with every respawn until I was left with the bare 3D-Model and a minimap that just showed the standard pattern the spawnpoints and the positions of my teammates.

I was able to finish the match, placed first with a score of more than 8000 and when the loading screen back to the hangar appeard, it finally stopped working and I had to close it.

I don't undestand anything anymore.
