Hey, just wanted to let you know this should be fixed now!
There are a few moving parts here: instances have a list of all languages it knows about, admins can restrict what can be used on the site (“discussion languages”), and communities can further restrict what languages they allow (if no mods speak Swedish, no use allowing it because you can’t moderate it), and on top of that you can select which languages you use in Lemmy’s settings. Alexandrite now respects all these settings/restrictions.
Some communities only allow posting in “Undetermined”, and Alexandrite defaults to selecting “English”, so if it was in one of those communities that’s why you were having issues. Should be good now though.
Yes, launching the game launches Ubisoft’s launcher and you have to sign into that to play.
Also if you use Proton it doesn’t auto close the launcher when you quit the game so it’ll run up your play time while the launcher is minimized to the system tray.
