In certain conditions bots will fail (or refuse) to build certain power poles on Gleba. This has occurred 'in the wild' to two different streamers in the last week or so.

It seems to occur when the polse is on a marsh near an iron stromatalite. My wild guess is that the smaller power pole hit box doesn't intersect with the stromatalite, but the landfill required for it does.

What did you do? Ghosted power pole drag.
What happened? One pole will not get built.
What did you expect to happen instead? All powers poles should get built.
Does it happen always, once, or sometimes? It seems to be somewhat rare for the right conditions to occur, but if they do the pole won't be built until the stromatalite is removed.

Derek MacIntyre also had the same issue in a recent game. I'll add a link if I can find it in his VODs

Here's the game that it occurred to Derek.

The actual discovery.
Then some investigation and discussion later in the run.

Oh and I had misremembered it was actually a copper stromatalite that caused the problem on this one.
