This was in Rain World: Downpour on Windows. Mods in use: Remix, Jolly Co-op, More Slugcats, Expedition. This was in the "story" gamemode. Player 1 was using a keyboard. Player 2 was using an old Logitech controller. At the beginning of each cycle, Player 1 would automatically switch to "any gamepad" in the input settings. Once this had happened, Player 1's slugcat responded to inputs from both the keyboard and the connected Logitech controller. This could only be fixed by returning to the input settings menu and setting player 1 back to "keyboard" each cycle. The campaign was "Monk".
#Player 1 is set to "any gamepad" at the very start of each cycle while using Jolly Co-op
