What did you do?

Built a lot of roboports/radars/poles/lasers in a grid using bots, some were over cliffs. During that build, my cliff explosives ran out.

What happened?

Some builds over cliffs got stuck forever, even when new cliff explosives were produced.

What did you expect to happen instead? It might be obvious to you, but do it anyway!

Once cliff explosives were available, the cliffs are automatically destroyed by bots, then the roboport etc ghosts are built.

Does it happen always, once, or sometimes?

I've only seen it once, but it happened to a few different roboports.

This first happened while I was running 2.0.41, and persisted in 2.0.42.

Do you know of any way to reproduce this from before the cliff got marked for deconstruction?

Actually, we figured out how to reproduce it. It's now fixed for the next release.

Thanks, I appreciate the quick fix! It was annoying to try and find all the stuck cliffs.
