this is actually the same problem that i posted about, it came with the new update

Make sure your game says v1.9.15 when you go to game options
Check if SplitScreen Co-op has version 0.1.15 in Remix mods list and that you can configure it
Disable other mods except Rain World Remix, Jolly Coop, More Slugcats expansion

one of my mods was breaking it ima try to figure out what was causing it to break

I figured out what was causing it. The mod "Sbcamerascroll" is causing this effect to happen.

thank you so much!!!!!!!!!!!!!!!!!!

SBCameraScroll was updated today. It will now work fine with SplitScreen Co-op
