Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition PS4 online coop achievements

First of all, love the game. I have it on steam, beat it many times. I've been playing trough the game on the PS4 with a friend of mine. first time through, we both got all of the trophies that we were trying to get. second time through, started getting trophies, but the day after we started, first player was getting trophies, but I wasn't. I'm the one who knows what to do, I led him through everything, but this time, I didn't get credit for 5 trophies, and my friend did. this happened last week. why didn't I get credit? we tried several times. both the ones for Brandon, returning to the surface, talking to icara about Leandra's plans, and the mangoth trophy. why was I denied those trophies? how do I fix this? we have been playing local co-op.
