Upon further examination, it looks like maybe unify is expecting that .pni file to be handled by stripe, as according to the error message, it's expecting to find the file on more than 1 server. It's supposed to be handled by dht though, and I've verified that this file exists on just one server, like it should.<div>

After upgrading to rc2, I'm getting unify errors for a lot of files. If I try to read one of these files, I get an I/O error.
