Kerbal Space Program

KerbalInventoryScenario is supposed to handle the ModuleInventoryPart instances created for in-vessel crew members through the ProtoCrewMember.kerbalModule getter.
However, at least in 1.12.2, the getter will bail out from adding those inventory instances to the KerbalInventoryScenario instance, unless the current game mode is SCENARIO or SCENARIO_NON_RESUMABLE.
I guess the conditions where inverted by mistake, although I fail to understand why there should be any condition of that type.

This cause ModuleInventoryPart.Update() to not run for kerbal inventories, which lead to the inventory not being updated when hovering them with a held part. The volume/mass limit sliders don't update, and the player can effectively entirely bypass the limits.

This also cause the whole kerbal inventory persistence system to fail in various ways, this is responsible for those two issues :
