I'm choosing to submit a beware on this artist in case they pop up again, I don't know if it's because of everything going on with Russia that they've disappeared, but I feel I've given them more than enough time to make things right.
On 16th August 2021 I saw their YCH of some cake ponies that I found super adorable so I decided to buy two slots that were sold together, I was told the files had gone missing so the YCH would take a little more time, which I'm fine with. I generally don't mind waiting for art. I paid for the YCH + tip and waited. Below is the YCH post, the comment chain and payment.
I didn't really contact the artist after this, figuring they needed a while. Eventually it slipped my mind with everything going on in the world, and I'll admit I could have pestered the artist for updates but as I mentioned, I don't mind waiting for art. I've learned from this though and try to keep up to date with artists nowadays. On May 5th 2022 I get a message on DeviantART from the artist, apologizing for being gone and promising to finish the art + extras. I replied with my refs as requested and waited. In June I followed up and again in July without any further reply from the artist. I gave the ultimatum in September that I'd be posting a beware, and I feel like I've given them enough time now to get back to me.
I don't think I'll ever get a refund or the art at this point, the last finished YCH is from Oct 2021.
