I used Bardin’s sitting emote at the end of a stage(Horn of Magnus), right before the screen transition, causing it to not show up, remaining on the in-game screen. All the sound cues for loot being received etc. still played, then after a minute or two I got a ‘sign-in timeout’ error and the game crashed. Subsequently I’d get the same error after opening the game.
Interestingly enough it also broke my network access to discord and twitch (and potentially more sites but I didn’t investigate much deeper than this) entirely. Restarting and verifying game files did not fix this (opening the game after verifying did bring up a windows checkbox about EAC so I suspect it’s culpable), but uninstalling the game entirely did. I’ll add to the post if the game is functional once it reinstalls.
EDIT: The game is functional after reinstalling.
