Repeatedly, on all three characters, when interacting with npcs in the tower (Zavala, Ikora, Hawthorne, Rahool, etc) i will be unable to escape from their dialogue windows (the ones you have to click or press enter for). Additionally, even pressing the escape key does not allow you to leave the dialogue, and you have to open your map and use the teleport waypoint in order to just leave dialogue. Not a necessarily game-breaking bug but Ikora is not close to a waypoint and when this happens 4 times in a row while trying to talk to her it can be quite upsetting. For addl. information, I am playing the game on Steam, haven't tested this bug on console. Video attached of bug in progress, and then the "fix" I have found.
