In Measure of Morality Part 1, in the final phase of the Trial of Esof 4, it's not uncommon for Control to appear "stuck" on some piece of the map geometry, which makes it impossible to lure it onto the platform -- which is necessary to progress the mission. This doesn't occur every time, but it seems to happen about half the time even when I'm making a conscious effort not to lead Control into spots where it's gotten stuck before.
My most recent experience of this issue was today (6/16 about 5:00 pm PT), with a level 65 delta recruit playing on Advanced difficulty. In this case, Control became "stuck" on a corner near the console closest to the magnetized platform. I quit and resumed the mission (restarting the trial from scratch) and completed it without Control getting "stuck."
