Agreeing with /u/AnEeedyatBoy. It seems the swap mechanic quickly moves the players across the pitch very quickly, having no collision with each other, and sending the ball up in a sort of "pinch". What's interesting is this isn't client-side, as the ball is not corrected to be on the ground moments later, but instead falls like normal. It also seems like once the count-down timer reaches 0, the physics on the ball reset to zero or something.
Calling /u/Psyonix_Cone for this bug / unintended behavior.
Also, while he's here, I have something to report about another issue that's irrelevant to the thread. After demos, the car respawns like normal, but if you are holding any buttons like accelerate, reverse, or boost, your client will predict them, but be denied by server corrections. Every time. This disrupts the flow of the game because it seems like your previous inputs don't get sent to the server during respawn anymore until after your car has respawned. This means that I can't preemptively move left/right and will always "lag" on respawning.
