Hey there! So the other night I was able to record a run with my brother. I had picked up an AV to HDMI converter so that my Elgato can get the video feed. Problem is about 12 minutes in the colours go all weird (in addition to horrible brightness issues):

(at 12:10) and (at 15:00)

This persists for the rest of the run, coming and going at some points. Here is a layout for how my setup looks: Never had this happen on our CRT TV, unless my AV to HDMI connector is faulty, idk what's wrong.

Offtopic: There are also no options for multiple players when submitting a Co-op run
