It seems like that day and time keep moving? It said I’d be able to change my main character to someone else after like 10:30 (my time, I’m assuming) today, but now I’m looking at it (after a nice breakfast, not pertinent) and it says like 18:30?
So ‘when’ can I change my main to someone else? I wanted to recreate that first character. I have everyone else fixed. 
I have the exact same problem, I made a character to test and now I want to delete it but can’t because it’s my main character. I just want the name on another character so I can start playing on it lol
You will be able to change your main soon. I’m pretty sure it was a bit more than a full 24 hours for me, but I just changed mine a few hours ago. I also would assume that it’s server time and not your local time.
I don’t believe there is any benefit to having a character set to main until you have a stronghold. So if you aren’t, I wouldn’t worry about it and you’ll probably be able to change it before you get your stronghold.
Thanks! It’s working now. Just surprised to see the time shift on me. You were right, it was probably 24 hours to when I actually crated it, where the original time was around launch.
I didn’t even realize that. What does the main mean related to a stronghold (assuming my stronghold is my housing)?
