The Game Changed My Server On Me!

I created a new account today (it's my 2nd one) and I chose the European server.
I played for a while then logged off, but when I came back on, it put me in the American districts.
I checked my account and it nows says the account is on the American servers!!
I don't want to just change it back to European cause it may happen again and ANet has that stupid rule to limit the number of server changes.

Has ever had this happen to them?

Thx.
