The game force-sold almost all of my cards simultaneously and autosaved, ruining a save file after months of play. This is a sad time :( I have no idea what instantly sells all your cards, but I sure have never sold a card on purpose!
This is a feature in the modded version. The mods have been discontinued a long time ago.
Do you know what triggers this behaviour in the mods?
Nevermind, saw it in the changelog you posted. Thanks, will try your version, didn't realize what I was playing was the modded one.
