[2.0.73] Bots being dispatched for deconstructing landfill before dispatch for entities on top

[reduke]

Mods: Elevated Rails, Quality.

How to reproduce: Stand next to an item on landfill with at least 2 personal robots and a roboport in a spidertron inventory, double click the entity on landfill with a default deconstruction planner

What should happen: The bot to remove the entity is dispatched based on the first click, then the bot to remove the landfill based on the second click, and they should arrive in that order

What happens: The bot to remove the landfill is dispatched first, before the bot to remove the entity, and they arrive in that order

Suggest to slow video down to 50% speed to catch the action.

Thanks for investigating

Thanks for the report however I am not able to reproduce any such issue. Are you sure a different robot isn't already on the way to handle the roboport and at a few ticks later the mobile roboport decides to override and take the job?

Also, can you reproduce this on a fresh standalone save file (that you then upload here?)

I didn't think personal robots could override other robots?

What do you need exactly from the fresh save? It will take me quite awhile to get back to having legendary spidertrons and robots

They can. It's internally called work stealing and it's done to speed up personal construction.

You can simply re-create it using the map editor or just use /cheat on a new save.

A couple of other observations:

I can't reproduce this when I am not in the range of any other roboports, but when I am in range and can reproduce this, my main roboport network has 0 free robots.

If it's work stealing, why does it happen for the roboport and not for the landfill?



Is there a time limit on work stealing? as most of the time I turn up at a construction site and I have to cancel and re-deconstruct everything to put my personal robots to work.

Will work on a fresh save probably tomorrow, thanks!

Ok, I haven't yet been able to replicate the dispatch order issues exactly as described in a clean save (I suspect your work stealing description is what is causing this), but I do have a clean save for you.

Use the custom deconstruction planner in the toolbar on the whole area under the wagon and watch what happens - robots are assigned to remove the rails and landfill long before they are assigned to remove the wagon. The only 5 bots that exist in the game are in your inventory.

Brand new fresh save from the editor - I cheated all the tech and the items and entities you see and did nothing else.
