Hi,
I have a really specific problem and i have no idea what could be causing it. Rocket League works fine in every other way except for one thing. When an unranked game ends our team goes to the post match training while we wait for the game to find more players. When it finds a game the game crashes instantly as other people join. If we search for a game while in this post game training and we join that game on another server it works fine. I've done all the usual troubleshooting stuff like verifying game files etc., although i am using old gpu drivers due to the current ones causing stuttering in every single game.
