In my case:
feddit.de didn't update and as soon as I switched to another account I couldn't login again
So I created one on shitjustworks. (which ended up with the same problem, but I wouldn't want to have a third sfw-account so I just waited until it resolved)
And I wouldn't be surprised if there was another old account of mine on feddit.de from a time where lemmy was just this weird thing some people in r/berlin linked to
I play vanilla java MC 1.20.1 on Steam Deck, no big problems with controller support (at least with prism launcher) Just the default keybinds are a bit shit, and there is no prev/next-item-key so you have to awkwardly scroll trough with the touchpads which is a bit meh during combat.
But I guess with a bit practice it's totally playable (I recommend peaceful to get used to the settings, tho)
