This Issue is maybe known, but i couldent finnd a Thread about it.
When playing Multiplayer on any Minigolf Map, there is a small chance that Wall Colliders do not work on the first Touch.
The Result is falling out of the Parkour and getting “Out of bounds”.
While playing around 20 Maps last weeks with my Friend, this happend 2 Times.
I cant imagine it beeing a Problem with our Hardware, also a Ping of 17 and a Jitter of 2 should be fine.
