Problems instantiating prefabs with skinned meshes?

I'm having a weird issue where an instantiated skinned mesh does not appear to be rendering only in Android output.

I ported my game over to U3b4 a while back to try it out, and I thought this might just be a pre-release bug, but I just updated that same old build for U3f2 and it's still not rendering.

My enemy character is instantiated via prefab, and I attach animationclips to it by script. It appears in the Editor and also in iPhone builds, but when I build to Android, the character is invisible. It's unclear whether the prefab is failing to instantiate or if the skinned mesh is simply not rendering.

Anyone else run into this issue?
