Two Quest Breaking Bugs…
First Bug: Mass Effect 2 & 3 LE
After using Shockwave on opponents at the Azure Parking Area during Lair of the Shadow Broker, an enemy was tossed completely out of the playable area. Unfortunately, the game didn’t register the area as cleared and my companions were repeatedly taking cover from this displaced enemy. Since the area must be cleared before you’re able to progress, all you can do is linger indefinitely, or reload a previous save. I guess falling over the ledge of a skyscraper isn’t fatal.
This also occurred during Priority: Rannoch, Destroy the Geth Base. I was being flanked from an adjacent platform (Tali calls this out). I used Slam and one of the Geth were knocked off the platform to the ground below, in an area that, until you clear the upper zone, isn’t accessible. My team just ran about, taking cover and aiming towards the ground below. Luckily, after looking VERY closely where they were aiming, I was able to shoot him and the game proceeded forward. Otherwise, you’d need to restart Priority: Rannoch.
Second Bug: Mass Effect 3: LE
When playing Priority: Tuchanka, there is an encounter just before a bride. Several Human and Rachni husks attack here, just after the fight with some husks and a Brute. If you use Biotic Charge to attack the last two Rachni husks at the tip of the bride, the area that gets split by the Mother of All Thresher Maws, you will get stuck within a large chunk of fallen debris, and you won’t be able to get free. Jumping will reveal your location but it won’t free you.
the worst part is, this is the point when the game will autosave so, if you get stuck here, you’ll have to restart Priority: Tuchanka. The autosave will just put you back inside the debris.
