I have found another Bug -- albeit a fancy one. The Shader-Tiling seems to be messed up -- these Moons should not be repeating, they should actually be clipped.
Also, it seems to me that there is an Issue with playing an Animation and waiting until it has ended, the Engine doesn't seem to wait properly, and it can screw up entire Animation-Chains. (For Example, my Character enters a Scene, walks up to a certain Position, should be playing a Turn-Animation and right afterwards a Kneeling-Animation changing the Outfit to a Kneeling-Outfit, then she should be saying a Line in that Outfit before standing up again and turning around again -- but instead, the Turn-Animations appear only for a brief Moment, the Kneeling-Animation doesn't play at all, she says her Line while standing, then suddenly is in her Kneeling-Outfit, with which she then moves around afterwards if I control her... it is all jumbled up.)
Those Animations have Action-Frames for changing Alignment and Outfit, if that is of any Importance.
(Sidenote: I have also updated my Windows to Service Pack 2 to see if it might help my Audio-Problem, but the Music -- and only the Music -- still is as distorted as before.)
