Aia's Gorgon and the altar
Long ago Aia created a gorgon of beautiful color, created in limited series and given as a reward. This creature was not meant to be upgraded via the normal ways, requiring impossible to achieve things. However, these same requirements caused severe abnormalities when sacrificing that creature. The wish and evo shop upgrade used to copy that level's requirements into the creature, and this is how a gorgon ended up with billions of won fights, something that ultimately broke the sacrifice altar.

All the gorgons (18 of them) got new stats. Their experience and won fights were reset to the exact requirements of the level they are at, so they are usable again. From here on they grow the normal way, by fighting, and they can be upgraded via wish or evo shop again. The alternative would have been to keep them truly unupgradeable and not usable in altars.

The sacrifice altar received also a guardrail to prevent sacrificing crits with such abnormal values, and you should see this notification on the creature page as well. If a better fix for these is to be made, i am open to suggestions. Maybe Aia comes back and decides what should happen to her gorgon.
