Imagine the following scenario:

1) I schedule some yellow belts to be upgraded to red belts using the upgrade planner
2) The yellow belts are destroyed by biters, which replace them with ghosts, which my bots then build.

Now the question is what the ghosts are. There are 2 sane design possibilities
a) red belts, which is what I obviously told the game should be placed there
b) yellow belt with an upgrade planned

However, the game places yellow belt ghosts with no upgrade planned. Which leads to random unupgraded entities in my base. This can't be the intended behavior.

Thanks for the report however that's working as intended.

Oh fascinating. So somebody sat down and asked "what kind of ghost do we intend to place when an item scheduled to be upgraded is destroyed". And then decided that placing the unupgraded item was the right and logical thing to do, the intended behavior.

Can you elaborate on the though process behind reaching that decision? It seems completely indefensible to me, and one should always be curious towards other people's actions which you do not understand, to broaden ones' understanding.

Maybe try not having biters running wild through your base in the middle of upgrading it. HTH

The decision was: if the action hasn't been performed yet then it hasn't been performed.
