Help -Stuck at Auxilary entrance door-

[hayama]

Got the same problem in Overture. I got my key and a gas can, used the saw on the wooden plank at the door and it's still closed. Pick Axe doesn't work.

Already tried reloading older save.

How do I open the these door? Is it a bug or do I do something wrong? Can someone send me a save after getting through the door to the Auxilary?
