Bug with Character BP capsule scale

I have a very large character. When I put the capsule around him, at some point it won’t scale anymore (up or down) and the character no longer responds to movement BP’s. I have to delete the Character BP and create a new one to resolve. Has anyone experienced this?

Not sure about the scaling issue, but make sure the “Agent Height” in Project Settings>Navigation Mesh>Generation is set to match your character’s capsule’s total height. If you exceed that your character will stop responding to movement calls.
