[0.15.28] Walls blueprint incorrectly deconstructs trees

[beiju]

Normal-placing (not shift-placing) a blueprint containing non-connected walls sometimes incorrectly issues deconstruction orders on nearby trees. It's incorrect for 2 reasons: first, I expect placing a blueprint without holding shift will never issue deconstruction orders. Second, the trees that are ordered for deconstruction are not blocking the blueprint.

Steps to reproduce:

1. Load the attached save file (vanilla, in a freshly created world)
2. Place the blueprint from the toolbar so that the furnace and belts in the blueprint align with the furnace and belts on the ground
3. Observe that 2 trees are ordered to be deconstructed

If you want to prove that the trees are not blocking the blueprint:

4. Clear the deconstruction orders on the trees
5. Get some robots and walls and let the robots place the walls
6. Observe that wall placement succeeds despite the trees not being deconstructed

I think I first noticed this in 0.15.22. I suspect the bug was introduced by the fix to this issue.

Thanks for the report. This is now fixed for the next version of 0.15.
