So I lucked out with my specialist right after getting his final perk by landing the permanent control + transfer-to-haven option on a Heavy MEC last night. Unfortunately, he didn't show up at any of my havens after the mission.
Of note, this was a haven defense mission in a non-liberated zone. I can also verify that this MEC was part of the enemies on the map at start, as this type of mission did not have a timer or any reinforcements. Also, the MEC happened to be the last enemy on the map as the mission ended right as I took him over.
Are there certain types of missions, such as the various haven defense ones, where you are not awarded the MEC?
Advent MEC not given to haven at end of mission after full override

Haven defense ONLY has reinforcements. Are you talking about the terror style retaliation?
Re: Advent MEC not given to haven at end of mission after full override
Yes, it was the type of mission with the civilians/ haven personnel you have to try and save before the aliens kill them all - main mission objective was to destroy all enemy troops with no timer.

Quick update, I just captured another MEC on a different type of haven defense mission - defend friendly supply train - and it also did not put the MEC at any of my havens. I saw johnnylump in another thread say its a known bug with certain missions and they're working on it, hope this info helps.
