Pet going home all the time

[Keyloqqinq]

Hi acs2005, 

I'm sorry you're having this issue.

This appears to be a common bug and there is no consensus on what causes it. 
However, the staff team is looking into it and for now, the best course of action would just be to buy a new pet from the cash shop. 
Sorry for any inconveniences

Also, in the future, I recommend joining the MapleKey Discord channel and posting your issues in the #support channel. The community and the admins will be more available on Discord to help you with your problems.
