Mines wont disarm even with all 3 standing under them is my biggest peeve, enemies glitching in and out comes in second. The worst was the time the door from the airlock just wouldn't open. When it runs smooth it's fine but when the whole thing fights you the entire way and takes forever just to get to skolas, it's not worth it, especially when there are other sources of etheric light and the cypher drops on 34.
