Artist sells regular monthly YCH auctions, purchased a spot at significant auto-buy price and paid promptly. Item was completed and no further contact from artist. This weekend the artist posted their latest batch of finished commissions and I noted that mine was posted - as well as another near duplicate piece featuring another character from the same base sketch. The artist resold the same sketch to a second regular commissioner without notification to the auction winner/original buyer. No mention that this was a possibility was in the auction terms, nor in any terms of service the artist provides. For the significant price paid, I feel it is reasonable to assume the exact sketch would not be reused as a base for additional work. Evidence below:

Second piece from same base: https://www.furaffinity.net/view/31414687/ (NSFW)
I did contact the artist and they did confirm that they sold the piece twice. All that was offered was an apology and statement they would avoid doing it in the future. However, I did note a second set of identical pieces in the recent postings - I cannot speak to the situation of those and will not link them here, but it gives evidence that this may be a recurring pattern and makes me doubt changes will be made to their practices.
While I don't expect any resolution from the artist (they did deliver a completed piece as commissioned), I did want to warn the community about the incident given the high profile of the artist and high cost of their work. Buyers beware.
