You gotta give more description on how your problem keeps occuring such as: What map do you play on that makes the glitch happen?
This happened to me only once and then it never happened again. I've also been playing 2 player split screen ever since the dlc came out and I've never encountered the glitch you are having.
Maybe try uninstalling the game then reinstall it afterwards. Don't worry about your progress in the game since your progress saves in the server.
Pretty sure something similar happened to me. Think the map was Sharkbite Shores when it first happened. Essentially it appears that your character spawns before the map geometry does. The geometry fills in after you spawn and you end up within the geometry. It's happened to me a few more times. I assume it's happened during Gnome Bomb and not Garden Ops due to the spawn point it happened at. I can't recall if this happened on any other map, either. That's just the one that came to mind.
Also getting disconnected and kicked from games more frequently since the update... that's Garden Ops and G&G.
