I'll take a look-see

could you make a mod that makes the rc builders actually build things when automated mode?

What's your location and the area where it usually happens? and you make it happen by? (I don't play the game so)

but before that I updated my fix bugs mod to hopefully stop it from happening, let me know if you have any more ceiling rubble.

Yes, I could selected the rubble. As time has passed, I see that it is map-related. On same map, multiple different games "generate" the same unreachable rubble., in the same place..

When you say rubble in the ceiling, do you mean rubble you can select?

yes, there are a few mods with new entities.

I can't load the save, you likely have a mod that adds new entities.

Hmm, second try to upload, here you go: https://easyupload.io/qkl8fi

It doesn't do anything for stuff near ceiling, just rubble nearish the ground (bout halfway up the edges), but too high for drones.

If you have rubble that high up, I wouldn't mind seeing your save file if you don't mind?

Hmm, not the right place to report, but I do have that mod installed and still got both unreachable by AI rubble and unreachable at all, high in the ceiling rubble,

Oh right, there's a fix for it in my Fix Bugs mod (it does it on load).... or it should do it?

Is a new save, started few days ago.

Pretty sure they fixed high rubble last update? Is it a new save or older?

Mostly works for me, unfortunately there are still pathing issues were only driving by hand could clear some rubble piles. Also, rubble spawning sometimes spawns rubble high up the ceiling, unreachable by anything, but messing the RC Dozer AI, which keeps trying to reach and clear. Haven't found any mod that fixes rubble spawn issue.

:) I did just add the wasterock option to it.

(facepalms) Man, I HAVE that mod, and forgot I could use it for that. I've been using RC Commanders to sweep areas into small dump sites and then letting the flyers collect them.

You use transport rovers to clear rubble.

Will they also collect and carry the waste rock to a dump site?
There's so much waste rock produced exploring and clearing the Underground, and there's very few concrete sites, so I've mostly been using WRProcessors to make concrete down there. Collecting the waste rock scattered everywhere is bothersome though.
