Hi, I'm here to report that starting any cutscene while being on a horse will render the character unmovable. Attempting to move it will give "please try again" message, and the character will refuse to move. The only way to fix this is by going to character screen and logging back in, or reloading the game altogether. Note: I always skipped the cutscenes before they ended. The bug occurred every single time I got a cutscene and skipped it while on a horse, so it is very reproducible.
