[BG] KAL-1000 losing tracks between hangar & flight (or game load/scene change) for anyone else?

[Beetlecat]

A modestly modded install of 1.7.3.2594 (though no mods that are known to deliberately interact with the BG robotics stuff).

This seems to match behavior seen in https://bugs.kerbalspaceprogram.com/issues/22728

I loaded a craft from KerbalX that had a Kal-1000 controller managing a rotor and a turboshaft, plus pitch values for the attached rotor blades, as well as thrust values for a pair of regular jets. Everything looked fine in-editor, but upon launch, nearly all, or all but one of the Kal-1000's tracks are missing. Launching the "known good" craft directly from the space center scene worked fine, but upon returning to that craft later (after a scene change or two) the tracks are missing again.

Just a preliminary question, since it totally caught me off-guard.
