Fixes:
fixed issues with the Blast Door hologram snapping to the tutorial elements and the construction plan (wrong/correct side);
the Blast Door is now correctly counted during the tutorial steps when placing and building it;
fixed the destruction behavior of the Blast Door — it can now be destroyed separately from the Doorway.
fixed the snapping of the Doorway hologram to walls during placement.
P.S. I didn’t expect the Blast Door to become the main source of bugs at the very start, but it’s now working as intended )
