I have been playing online co op with my friend as the host. I am doing the requirements for the trophy and he is getting it and I am getting nothing. I do not want to play if I am not making progress. Both parties in the game should be getting the trophies that are unlocked. IS this going to be patched as I don't think I will play until it is.

I played couch coop on PS4 with a friend, my friend signed in on the "guest" profile option on PS4. No coop trophies popped when playing together despite both us on normal and meeting the requirements. Worse still in single player many trophies were glitched as well with only the complete the game one a popping for me.

However, when I deleted my.save file and then tried, the trophies then unlocked.

In local co-op, the second player's account is fully ignored even when logged in. This means the second player can't unlock any unlockables or achievements and progress further

My brother and I got the elf chaser achievement, it shows in the achievement list in the game menu as unlocked correctly, but it did not unlock on my brothers steam achievement. Mine worked as intended.

I created the game locally, random normal, played with 3 people for about 15 floors, then saved and quit. Later, we continued the game but with me locally creating the game, and player 2 and player 3 joining me online, both playing on the same pc, couch co-op local style. We then finished the game, both of them died and I was the only one alive, they were ressurected when I got the last ship piece, and they got the achievement as soon as we talked to lamont and started the party. I never did, even after credits. Gonna try again at another time and let you know if I have any more problems with it.

Not sure if intended but I've had achievements triggering when someone in coop gets them. For some this makes sense, but for others such as dying in a certain way, it doesn't. This was on PC.
