Making an arbitrary number of new identities will eventually cause the circuit view in Torbutton to show the wrong exit node.
This is a screenshot I took to show the problem. Notice Torbutton thinks my IP address is 126.96.36.199 and in Canada. check.torproject.org says it is 188.8.131.52 Atlas says that exit is in France
When testing this I found that the number of new identities that are needed to reproduce this varies. Sometimes it happened first time other times I spent 10-15 minutes creating new identities in order to 'break' circuit view.
This has been happening over multiple versions of Tor Browser and doesn't seem to affect anonymity because the ip addresses are always Tor nodes. So it is not 'breaking Tor', just the circuit view.
Is this a known (or unknown) problem with TorButton's circuit view, or have I misconfigured something? Or something else entirely?
