 }}}

 Understandably, the storage node is balking at unsigned announcements.
 However, in this case the unsigned announcement was fourth of 22, and when
 the error was thrown, it wasn't caught anywhere. This meant that the
 storage node would only initially find 3 of 22 peers.

 For my custom introducer, I am resolving this by faking signatures for the
 1.9.2 peers in the introducer server code, so the two older storage nodes
 are still usable. But I think this is technically a bug in the introducer
 client code.
