I use my Google ID to log in. The first time I logged in this morning (about 30 mins ago) I got the welcome new user message and I'm taken to an account that's empty with no record of any transactions. If I log out and back in I get the welcome back message and I'm taken to the same empty account. I'm pretty sure that the User ID and the id= string in the Google OpenID that are listed on the profile page are different to what they've been before today, even though I'm logging in with the same Google account.
UPDATE: I've cleared my cookies, relogged in to Google and relogged into Britcoin and I'm seeing my correct account again. The User ID is back to what it was before. For some reason I was being recognised as a different user, even though the Google account I was using was definitely the same one... Any ideas why??
