The site functionality issue is being shown a night chibi zentu when I used the chibi potion despite my pet being a day zentu.

I just changed my pet Neath in to a common day zentu and then a chibi. When I used the chibi potion I was given a screen showing a night chibi zentu

Your pet has changed into a Chibi Zentu! Back to your items!

I started to fill out a ticket to ask for Neath to be changed to the Day and went to his profile to gender check (I've been changing lots of pets and couldn't remember if he was a he or she) and discovered he is indeed day.
