strange bug.
in solstheim, when im supposed to tame the first dragon inside mora's world, i can shout at him so he lands and asks me to mount him. once i do i see the animation of my character mounts the beast and then the dragon picks off and flys.... without me. im still hovering at the exact same place where i sat on the dragon's neck. i can see my character turning and yawing as if it's on a dragon but the dragon itself is flying away without me.

obviously i cant continue the quest to kill miraak since i cant get to him so im stuck.
i tried to think what mod caused this so i disabled "convenient horses" by using the console and then removing the BSA and ESP but that didnt help at all.

also i will note that the first time i saw miraak in a vision in the beginning of the quest he also mounted a dragon to fly on his back but the same issue happened there - the dragon flew but left miraak sitting on air.

anyone has a clue on what might cause this and how to solve?

I hear it's an incompatibility with mods that alter physics, for example "realistic physics"

Also, from a few threads below about how to fix the same issue:
