Entry guard node always United States
Suspect that US gov't has found a new way to link traffic to Tor users...
Noticed that every time I started v6.0.5 on Windows, entry guard node was consistently United States. Even after doing multiple new circuit requests, entry guard was always United States. Middle and exit nodes changed when new circuit was requested, entry always US.
Deleted the Tor browser folder, reinstalled v6.0, updated it, now working normally.
I can provide the deleted Tor browser folder if that helps.
