I can’t ride my mypet even though I chose the /pcst as ride. I could ride it before, but now I can’t.
The mypet bug has been fixed. If you're under the Noble rank then you cannot ride pets as you need the Noble+ rank to ride them. Are you Noble+?
Ohhhh I see. I was not a noble but I was able to ride it, but not anymore. That explains it, thank you!
