[2.0.77] Certain module ghosts not properly requested when using Upgrade Planner

[ohowun]

Version 2.0.77 (build 84539 expansion, win64)
Playing with Krastorio 2: Spaced Out mod and required dependencies, plus Milestones, Belt Visualizer, trainsaver, and Visible Planets In Space mods.


1. What did you do?

Used an upgrade planner on mining drills.
The upgrade planner was set to upgrade electric mining drills to a higher tier one with more module slots (with the same building footprint, K2), and had module requests in the first and last slots of the upgraded building.
Ore patch was not within roboport range but player had roboports.


2. What happened?

Some module ghost requests did not seem to be made. Others appeared correctly.


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

I expected all the modules to be requested in the correct spots, or at least for all the mining drills to have their upgrades/requests made consistently.


4. Does it happen always, once, or sometimes?

Able to replicate by simply undoing/redoing. Have video footage of one example, however, initially had a different set of mining drills with missing module requests. Was not able to replicate the change in mining drills with missing modules.

Problem was replicable while using Ctrl Z + Y, and also with different upgrade planners configured the same way. Canceling and re-making the request (instead of re-doing what was undone) also replicated the problem.
