[0.15.12] Personal Construction bots won't construct (outdistanced robots) MR

[Brambor]

Robot's wont construct fast inserter and yellow belt when I tell them to, placing one of my blueprints.
There is also curved rail to be constructed which I don't have rails for. I'm playing on the Marathon map.
It happened more times on that map and it is getting annoying.
I'm attaching save file.

There is not a single open construction job in your save, and if a place a fast inserter ghost it gets placed immediately. Post a save with open construction jobs that do not get completed please.

Crap, sorrry, uploaded the wrong file, ups...
There's the right one now.

You outdistanced two of your bots, now they are out of energy and are trying to get back to you. Wait at that position for a few minutes and they will recharge and place the inserter.

Crap, I just read a post and originaly submitted this under it starting with:
"I have the same problem but it actually is a bug."
Well then, any chance that this would make it through suggestions? (if robot would take more then 10 secs then new robot will be choosen for that task) ?

The implementation you describe would not, simply because gathering the information on how long will it take for any robot to get to its destination would destroy performance.
What I could imagine would be a warning for robots out of energy, but I would think such a suggestion already exists though.
