I'm trying to start an auction to sell one of my wolves, but it isn't working for me. I try to set the date to today, and it says I can't start an auction in the past; I even put in tomorrow's date and it didn't work!

Have you maybe tried adjusting the time? Because if you set the auction for today but it's already past the time that you set, then it won't work.

Have you tried Changing the time. In this game time for some places in the world like mine, the clock is two hours ahead to ours or try typing where the date and stuff is
