I am aware of the Varren issue, but this was the entire mission with Garrus just constantly stuck in place from intial landing to the end of the mission. I've never seen that before, I've had the occasional stuck character but it always fixed itself after a while or by entering a conversation or triggering a cutscene. This time Garrus just stayed stuck in place. Even when it was fixed by dying and reloading, it would happen again at the next cutscene or convo. It wasn't a big issue overall, but seems a surprisingly big thing to not have fixed.
Like I said though, it was only Feros this happened, never happened on any other main or side mission to my knowledge. Just a weird bug that I would've thought they'd try and fix. Or maybe they did try IDK.
