LAMH fur does not pose with model

LindaB

I'm working on a scene with AM's mouse, I have two of the mice in the scene. The fur on one of the mice doesn't stay attached to the model when posing. I move the leg, but the fur stays in place. However, the fur on the second mouse DOES move when I pose him. When I first loaded both mice in the scene, they both worked fine, but then the fur on one of the mice just stopped moving when I pose the model, and I don't know how to fix it. This problem with LAMH models has happened before. What causes the fur to become separated from the model? Is there any way to fix it and get the fur to start working correctly again?
