Crash while using extended CharacterMovementComponent

I’m still getting a (non-fatal) error when I reopen the project. I get a nice big red:

LoadErrors:Error: Error Failed import for MonsterGameCharacterMovementComponent

In the output log.

In the message log, I get:

Error Failed import for MonsterGameCharacterMovementComponent /Game/TopDown/Blueprints/TopDownCharacter.Default__TopDownCharacter_C:CharMoveComp

So, it seems like a blueprint issue?

Hot reloading works fine, however. Is there a way to debug this error? (As it is I have to hot reload the editor to update the code)

Edit: It seems like explicitly saving the blueprint with the extend code in it fixed the problem? There’s gotta be a better way, though.
