A bug I suppose you could call it that I encountered, or more of just an Immersion break, is that if you go back to Vox Relay, Virgil will still be standing there inside, even after completely finishing Tristan's questline and killing Virgil.

A bug I've experienced is that if you're on Inez's companion quest "Full Measures", and progress far enough in the story that you choose to go against Auntie's Choice and lose access to the ACS Undisputed Claim, you do not fail the quest, nor do you have the ability to finish it. It just stays in your quest log uncompleted.
