Can't get out with the Treasury (Dishonored 2)

Sit play, chose Corvo, 1-mission took the ring from Ramsey, went opened the Treasury and took all that you can put the mask on. tried to come up with it did not happen that does not happen. There should be a choice to remain in the Treasury or go out, that's exactly it is not. Corvo says something when you press, that is responsive but equal does not. Anyone seen this before.
