Am I going crazy or was this a mistake?

as far as I know, it's been on sale the whole time, but I hadn't bought it just yet, was trying to figure out which games I would get for my budget. I think it was under 20 bucks for the obsidian edition, and now it's over 60.

I wouldn't strike it as weird if not for the other obsidian games being on sale, including Tyranny and POE 1.

it must have dropped off the sale pretty recently too, because I was keeping an eye on it. what happened?

Image is as it looks now. it looks really weird to be the odd one out.
