Detail Shadow Map Artifacts

Has anyone seen this happen before?

I have detail shadow maps turned on and they work great! Mostly. The shadow definition for the hair is great especially for the hair, but it's not aligning properly around the nose. It's like the shadow is offset so the parts closest to where the shadow should be are not shadowed at all.

I realized it must be the depth map bias, but adjusting that doesn't fix it. I tried lowering all the way to .001 and it won't get any smaller. Lowering to 0 just sets the default to .02 from the 'Render Options' setting which makes it worse.

Anyone have any ideas? Thanks!

--Edit--

Nevermind, sorry. I had renamed the light, and MR couldn't find the shadowmap file because of it. Talk about finnicky.

What type of light are you using? Try a spotlight or forget about it and raytrace.
