strange(?)behavior of FumeFX with an animated Windeffector

[useruser]

hello,
here is a projectfile + previewrender. the scenefile included an animated windeffector.(slow rotation from right to left) for me the movement and behavior of the fluid looks a bit strange and not correct at all. as if fumefx does not interpreting the changing direction of the windeffector correctly.
thanks in advance
