I don't quite understand where you think we might have gotten things mixed up. Saves are automatically transferred from one version to another, so if you have played previous versions, you should still have your old saves.

Ah, yeah, I'm aware of the save file transfer, that wasn't what I meant. I already had v2.7, played it and then downloaded it again and noticed the same version number, so I went to check when I last played.
So, TL:DR I'm very certain you had released v2.7 somewhen around late January/early February 2024 and are now releasing it again.
