KSP - 2023-11-14T084904.662.log

This could be related to #354:

[WRN 01:44:32.295] InternalModel error: Part Crew capacity is 10, but 0 seats are defined in internal model
[ERR 01:44:32.295] [FreeIva] Could not find a centrifuge module in INTERNAL 'sspx-expandable-centrifuge-375-2-iva' for PART 'sspx-expandable-centrifuge-375-2'

If there were no seats because the internal model was destroyed, this could probably happen...but it might also happen when boarding a part that has more crew capacity than internal seats. But the PostBoardCoroutine wouldn't have been started if the kerbal didn't have an internal seat assigned. But maybe if the portrait gallery was full, the internal model wouldn't have been created?

Gonna mark this fixed, but I'm not confident. Will reopen if it pops up again.

Seems like this was likely caused by #356 - when the internalcamera is destroyed, trying to activate IVA mode will spew these exceptions.

This will still occur if some other bug destroys the internacamera, as in KSP-KOS/KOS#3095
