So I went to start a Dark Agartha run. Clicked the orb thing and while it was “casting” I decided to reload my UI at that very moment for whatever reason. Now I’m stuck. The UI reloaded, but the Yes/No modal dialog box is gone and I’m frozen in place with all abilities greyed out.
EDIT: After some amount of time (however long it took to come here, read some notifications, and then make this post) my character was released. Guess there’s a failsafe built in.
