Anyway, I missed a feeding due to ISP issues, so I would blame myself. Except there was enough grass for it to eat, and there's still grass in the pen after she died. See the image (no, I didn't replant any grass, I just filled the through now):
Any chance of getting her revived?
*edit*
And now I've observed my bulls eating the grass even though I had filled the through. There's something seriously buggy here.
