I'm using Mighty 6 right now and have experienced the same issue. While I don't know how to "fix" it, it should go away relatively quickly (within a few hours or so). I've only encountered this when I've taken my phone to a different location (say California to Colorado) where my reception isn't as good. Doing a soft reset hasn't solved it, but if I leave it alone for a little while, it seems to fix itself. Contacts come back, TF3D begins to work again. That's just my experience though.
