Not sure if this is a bug or working as intended, so I figured I would report it. When "Show all items in selection lists" is unchecked, if you look at the burnable fuels: it still shows fuels you don't know about. This screen shot is from before leaving Nauvis.

This occurs if you alt click anything behind the Factoriopedia. If you open your inventory and alt-click on an item then try to alt-click on another item, it also selects the ground under the cursor. Same for trying to alt-click on something in the world (assembly machine for example). It appears ...

I was trying to get my mod to work on ghosted entities and I think I found a bug. When I added code to check the ghost_type to confirm a belt on an entity-ghost, it marks everything for deconstruction if you start on a belt, even the ghosts get marked for deconstruction, which then causes a crash if ...

As I am making a mod that recurses thru all belt_neighbours to mark for deconstruction or upgrade all belts in a chain, I would like the users to be able to undo the deconstruction or upgrade like you can with the normal deconstruction and upgrade planners.

Can you either add to the undo list for ...

1. Guess its time for a request then.
2. Apparently I was referencing the inputs and outputs incorrectly...awesome, so much cleaner than the crazy facing code I wrote.

Thanks for the help!

I am making a mod to make chain actions to assist in non-linear deconstruction and upgrade (e.g. your belt isn't perfectly vertical or horizontal). I have two issues with this.
1) order_deconstruction and order_upgrade do not create undo orders, so my deconstruction and upgrade actions cannot be ...

Then should undo work on a rotation caused by overwrite? The two are functionally identical despite being sourced from different actions, yet they react differently to undo.

If you place a ghost object, then rotate it, then undo, the ghost is removed, not unrotated. This is very odd when placing a row of belts and rotate one part way thru (maybe by accident) then undo and the last belt placed is removed rather than the rotation being undone.

Undo does work properly if ...
