Seeing: "Got REQ_KEY from XXX while we already started a SPTPS session!"

[Andy Burke]

I'm running tinc 1.1pre11 with AutoConnect set to 'yes' and I recently
started seeing lots of these messages on my VPN and cannot connect to
various hosts from other hosts:

I have also seen messages about mismatched seqnos, but I've lost them in
the logs since I noticed them last night.

I've googled around and have not seen anyone else have this issue. Can
anyone give me some guidance on why this might be happening?
