[WRN 00:53:48.810] Model load error in 'E:\game\Kerbal Space Program\GameData\KFC\parts\FRX00\Yukikaze.mu'

The log indicate a loading error. It is only a simple transform animation. Is it related to I didn't use any animator in models?

Edit: Add animator, the model go through, but the animation doesn't works.

And the legacy flag of the animation doesn't affect the result.
