I think my game has reached a point where it can't progress any further.
I am about 10 months in and I have researched everything. Early in the game though I never caught a sectoid, the troops were too zealous on over watch. There have been no sectoids for months and I can't research past the interrogation.
I've caught a thin man and an overseer but haven't been given the opportunity to interrogate or research them. I am assuming that I need to do the sectoid first.
Am I stuck and need to start over or should I continue to hold out and hope they show up in a future mission?
