[Genhis][2.1.7] Upgrade planner on space platform ghosts will not request new ghosts

[DeHackEd]

Build a space platform. Place ghosts that cannot be built. Use an upgrade planner to convert those ghosts into something else (I went with Epic Accumulators => Normal Accumulators).

Expected behaviour: platform requests the new item (normal accumulators)

Actual behaviour: new ghosts are not requested.

I also upgraded ghosts with upgrade planner but somehow a few entities are not requested even after re-building (See on video)

I was able to reproduce this issue.

I imported a old spaceship that utilized blue belts --> used the upgrade planner to change the belts to red belts.

Space platform does no longer request the red belts.

I tested it with placing some yellow belts, and upgraded them to red belts, the issues persist.
