I reload from even entering the final facility you have to build to proceed to the last mission, and STILL I can't pass those freaking doors. I reload from before the mission launches at base, same problem.
I reload from the beginning of the mission, and same problem. I check the 2K forums and they say reloading the save will help resolve that issue. There are 3 of these and the first time I couldn't pass, all I could do is stand in front of it with no option to opening the door (via V or left click). I clear out the first room and approach the next set of doors which are one tile into the wall, as opposed to be flush with the wall. After playing (this fantastic game) for almost 30 hrs I methodically made my way to the final mission.
