Son of the Devil

Good map, but here's the problem: the time came to emerge to the surface, the heroes took their places, and even when reinforcements appeared, I didn't move them, so as not to miss the moment of the transfer. Then a cutscene appeared, saying that it was time to move forward, and... nothing happened. The heroes remained underground.
Just in case, I didn't move them for two weeks, waiting for the transfer - nothing happened. I tried to move them around - I can move them, but I still can't get to the surface. What should I do?
Yes, and just in case: I didn't find the Tear because I couldn't clear the rubble. I didn't have time to return the Star, it was time to move the troops to the designated points, but aren't these all secondary tasks? Why wasn't I transported to the surface?

Otherwise, the map is great, I really like such maps. I just wish I could get to the surface...
