Bug in lilith's room after last mission(spoilers ahead)

after returning to sanctuary and going to lilith’s room, while standing next to the bed and waiting for ava to finish her speach, i didnt notice her start to walk towards me and she walked right to the same spot i was standing in, and stopped. i couldnt move, tried jumping away, crouching, even killing myself(her and tannis just revive you). finally had to log, tannis had already opened the chest which held an orange item i couldnt take.
