ufoai-2.3 rev 30745 Tropical Harvester bug again?

[Kobold]

i played today the tropical map and i saw the changes in the new version about the harvester ufo, i cant enter the second floor in the ufo cause there are no longer stairs o.O
im a little bid confused, i though you fixed that ufo?
when this is expected that are no stairs to the second floor, the aliens cant spawn on the second floor at least?

i post here now 2 screenshots but the brightness messed up, so i inverted the colours from the screenshots...

That harvester is completely messed up
You're not just missing  stairs but also walls etc.
No clue

I am pretty sure this will be repaired by some experienced mapper soon.
