I have two major issues I found while playing multiplayer:

[Major Issue] My boyfriend was the host computer. After finishing up the helm section on the ship, I loaded into the beach area faster than he did. I walked around for a bit, then after his game finished loading, we were sent to the cutscene. The cutscene did not play for him, but the audio did. It played fine for me. So there seems to be some issue where, if the host player loads in last, they might not get the cutscene.

[Major Issue] In a three player game: When we ended the game then started playing again, the third person who tried to join the game got the error "No available characters to control." This didn't seem to be a computer issue, as I swapped and loaded in later, he got into the game while I got the error. Because of this issue, we're no longer able to continue our save, which isn't all that great. We want to play!
