I am finding that updates to the model XML’s and also model updates are not
always showing up. In particular, animation adjustments in coding in the XML.
When rebooting the sim itself, it will finally show up, but if you are in the
sim, pause, ‘Build’ the plane again, the updates are uploaded into the
Package, but not visible in the sim. Even if you leave the flight to Main
Menu, then return, the updates do not show. When rebooting the sim completely,
it shows. That alone can take several minutes. Radical time eater. 
I’m not seeing this here, everything is behaving as normal. Just a thought,
but do you perhaps have a version of the same aircraft in your community
folder?
Have you tried the “Quick reload” Button in the Behaviours debug panel ?
