Tonight I have experienced several ‘Critical Error’ crashes with my client where, in the middle of a game, the client just dies with the super helpful ‘critical error’ message, and I’m kicked back to the menu.
It has happened when I’ve been smokeshowing* fools, been being crushed into oblivion, and even when just idly hanging out. I haven’t noticed any sort of consistency, other than actually being in game. To that point, I’ve seen it happen in the first round of a match / and or the second map.
*Very rare sighting, but it happens on rare occasions.
