Unfortunate Co-Op experience

So this one person joined my world today, they were super chill and we hit it off talking about world quests , exploring etc . So then after a while , they were trying to find out the hot air balloon in chasca's tribe area . The problem is, I play on GeforceNow, and there is a 1 hour session limit . So my session was about to end , so was trying to type it up and just about to send it when the game ended . I feel so bad, they might probably think I kicked them out . I send them a friend request but haven't accepted it , idk it's such a wierd guilty feeling.

Have you guys had any unfortunate incidents in co-op ?
