I had nowhere else to place this thread. I would not call it a bug myself, and I say that on a peer level. However, if this was MY work, I would quickly notice I forgot to do something correctly.

Take it as it is.

Daytime: Yes
Per-Vertex Lighting: Yes
Place honey in a bucket. Stand still at idle state. As the animation plays through each key frame, the texture, *cough* diffuse area that is the honey will cycle between vertex lighting, to not receiving vertex lighting. Due to how fast the animation is, it creates a very noticeable flickering/flashing effect.
You can also notice a similar effect on leather boots, however this is due to the boots and feet fighting for draw order/depth buffer. One would imagine the feet as a separate mesh that is disabled when boots are equipped. But I digress.
Again, not bugs. Shall we just say
shoddy?
