The replay above is for r17131.
This ticket sounds like a duplicate of #3471 as units here are also stuck without touching any obstruction.
If you replace the construct order with an identical walk order in the minimal replay (attachment:commands.txt) then the units will not be stuck.

So maybe it has something to do with new obstructions not being taken into account correctly.
