At various points throughout the game, a character’s dialogue audio will simply not play. You may end up with a one-sided conversation, a completely silent conversation, or a conversation where characters’ dialogue audio pops in and out. Has happened during cutscenes and non-cutscenes alike.
Also, with the fast travel notice being put in the lower righthand corner (an area easy to dismiss/not notice in this game/the small text/UI issues people are reporting), the game could use a louder and more distinct audio cue that fast travel is about to happen (particularly for multiplayer). The current audio cue is too quiet and doesn’t stand out enough like the cue in BL2 did.
