I also encountered the same issue. The first giant warehouse constructed at the bottom cannot be accessed by a ladder to connect to the road, whereas the second giant warehouse stacked above it can be normally connected to the road via a ladder.

Huh, I haven't considered stacking them; maybe its a height thing? I'm going to try taller supports under the bottom warehouse.

I think I have identified the problem. I just tried filling all the 7X7 blocks at the bottom of the giant warehouse with platforms except for the ladder in the middle, and then the road connection can work normally. Afterwards, I directly built the giant warehouse on the ground and connected the road from the entrance above the warehouse through an external ladder, which can also connect the road normally.
I suspect that there may have been a change in the building judgment after the update. In the past, the construction conditions for a giant warehouse were that there were 3X3 supports on all four corners. Although the construction conditions have not changed now, using only 4 3X3 blocks to support the bottom will result in the problem of not being able to connect to the road. It is necessary to have supports in all the grids below to connect to the road properly.
Of course, this is just the result of my own attempt. If possible, you can also try it out and see if the result is the same as mine.

@morbiuszero, I tried your technique and was able to get the on platform method to work, but nothing I do gets them to work on the ground (or stacked the old way with ladders up the middle all the way).

The old method of building ladders through the giant warehouse does not connect any more. In other words, the only way these mods work now is to have only one of them, built on a platform, with a ladder in the middle instead of a platform. 48 platforms, 1 ladder in middle works to get up into it.

The only way I could get to stack them is to sandwich a layer of platforms in between. So it goes platforms with ladder -> warehouse -> platforms -> platforms with ladder -> warehouse ... and so on upward. with external ladders connecting into to those platform with ladder layers. chaotic... but its a workaround =)

FWIW my experiment with heights bore no fruit. I will try supporting the whole grid area and try again.

Now it needs to support four 3x3 corners, 1 blocks in the opposite direction of the entrance arrow.
That's also why it can be connected when built second, as the first one has already provided all the support.

Not sure I understand you exactly? I get the four 3x3 corners but not exactly which block to support: the one behind the ladder? The one on that edge?
Or something else?

Just found this thread and I've discovered its the top option, but the arrow facing the other way. You need to support the block the arrow is pointing away from.

Fab, thank you. I will try that out.
