Wing folding on default 747

Hey gents,

How in the world is something like that possible : I have the wings of the default 747 folding up and unfolding in a circular manner (Cannot include link for the video of it here)

I have absolutely no clue on how this can be done, yet in my small program I achieve to do this… It is multi threaded and I change a lot of Simconnect vars.

However, I do not touch anything remotely related to wing folding… And unbeknownst to me I touch probably one var and this keeps happening.

Tough to debug as I cannot reproduce this bug.

If someone has an idea how this could happen?
