Should I choose New lobby or Restart when moving the bot?
New lobby asks the selected bot to leave its current party. Restart reconnects the bot; choose it for a connection problem, rather than simply changing groups.
Move the bot
Select New lobby, then check that the bot has left the old party. Invite it from the player who will host the next group.
Recover a connection
Use Restart for a stuck bot connection. Wait for the reconnection response before trying another party action.
Recheck the lineup
After either action, compare the bot's Epic name, members and leader in Fortnite. Neither button reserves a private match.
