Researching a Bug: Entering vessel load range, triggers multiple vessel trim bug

[Rpatto92]

Basically as the title reads. I spawned multiple vessels with vessel mover, flew out of, then back into load range of said grounded vessel and doing so caused the vessel I was flying plus one ground vessel to set the trim settings to maximum downward pitch/right roll/right yaw. (pressing alt-x still resets the trim, partial workaround, but my ground vessel still takes damage)

Also maybe worth a mention, I had reloaded/saved multiples times prior to this bug. At one point I ejected a Kerbal, landed with vessel mover, moved the Kerbal with vessel mover back to board my vessel, saved and reloaded. The Kerbal also despawned upon load. I included this as, in doing some research I found multiple players suggesting that the control bindings for Kerbals sometimes cause conflicts resulting in the control of multiple vessels and that this may interfere with trim. I have however rebound said Kerbal binds and tried reloading the save and have still replicated the bug, whether this would still occur on a fresh save without a reload IDK.

I had another vessel following my own in-flight which left load range and despawned, however the bug still occurs with the following vessel loaded without having first despawned. So I think it's possible to discount these variables. 

Will provide logs if needed.

I suspect that one or more of the following mods may be the cause: BDAc wing commander, Vessel mover, Physics range extender (set to 10,000), and Plane mode.

Did a fair bit of research before posting, and I found some clues but nothing definitive. I'm hoping forum users can provide me with something more to go on, to discover the exact cause and perhaps a uncompromising workaround or at-least be able to inform the relevant mod developer/maintainers.
