My account overview shows that this pet sold for 18 gold https://www.sylestia.com/view/pets/?petid=981309 and this one sold for 7 gold https://www.sylestia.com/view/pets/?petid=1122914
Additionally several of my pets are set for low gold amounts, such as this one which was set for 4 gold before I removed her from the market https://www.sylestia.com/view/pets/?petid=1235062

The issue being that they had all the zeros removed from their price for some reason.
The first was set for 18,000, I remember even double checking to make sure I had the right number of zeros, the second was set for 70,000 and the last for 40,000.
I'm mostly confused as to why the prices had changed.
I can try to get screenshots if you'd like, but my access is usually largely limited to my phone, and I'm doubtful that I could post a screenshot from it.

Edit- just searched my pets and it seems these were the only ones that weren't right. I'm not really sure why it only changed these three and not more, as most of them were priced around the same time.

They most likely were ones that I had to restore and they were rolled back via Friday's backup and for some reason I guess it cut the 0's off.

I can't really do anything to correct the prices... so you'll just have to check and make sure all of your 'For-Sale' pets are marked correctly.

I apologize for the inconvenience.

It's alright! I wasn't upset about the lost gold, I just wasn't sure if it was an issue that was more widespread or not, so I thought I'd mention it. Best of luck with all the issues and thank you for all the time and effort you put into this site, you and Fai have made it wonderful!
