PS4 [HELP] Wanting a new friend to join a game.

[agentxkentucky]

Howdy! I'm new to stardew valley on ps4. My younger sister and I started a game along with someone else and are really far into the game. We had another friend join but they don't play stardew as often so we decided to have our other friend, who's on more often, buy the game and join our world but the game said that that player character is already taken and I was wondering if there's a way we can add him and or a way around that.
Thank you.

Do you have a cabin built for the friend that bought the game recently? If you want to kick the other player, also, you just need to delete their cabin
