So this is a problem that has been bugging for over a year now. In coop, the courses seem to randomly not lock for one partner, or in the middle of the run just be unlocked at random. Also, the cutscene for course 5 appearing sometimes doesn't play because the course is already there, even though it's still locked. Does anyone have any info on this or even better, any method on how to prevent this?

I've never experienced this :/ Were you locking the maps as Blue ?

Have you been restarting your game when you restart your coop adventures? Imita makes me do this so it might have some value for fixing this problem if you don't do that

I know that course 5 is still there when you enter it and then don't quit the game before restarting, so I always do it then. But in every other case I don't. I'll try restarting game I guess. Also @PacK both players locked the maps, but sometimes it still doesn't work for one player.

GooMan, then you are just cursed :/

So if somebody with deeper knowledge of the game wants to look into this, I just did a run where, again, course 5 was suddenly there. In all the lobbies before, the unlocking of the courses worked just as it should. Before that run I did not enter any chambers, I only reset during Calibration. (Last demo is the lobby after course 4 btw) https://www.dropbox.com/s/10i8d89nwo5352w/unlock%20inconsistency.rar?dl=0
