Major storybreaking bug

[SurDno]

If during the first tutorial mission, you'll manage to get to the Pump Station before the blowout begins, the 'Return to Clear Sky base' quest becomes finished (instead of cancelled) and you don't teleport back to Lebedev. If you get to Fishing Farmstead's guider, he would say that he can't guide you anywhere and it is impossible to continue the plot.
