I didn't crash when I entered multiplayer with no one recruited. it allowed me to recruit though you couldn't see any of them in the world unless recruited but could only recruit 1. the crash seems to occur when entering multiplayer with a party of 2 terra guardians or more and then you try to dismiss any of the group since you only see 1 companion showing. though i did have to tell all them to move in so possibly they just hadn't shown up in the world. since upon dismissing the single companion I recruited in multiplayer after entering multiplayer with no party didn't crash me. it seems to be a problem with having multiple terra guardians in a party before entering multiplayer.
