seems like we got a little bug hiding somewhere.
but, after checking the DB it also seems there's everything fine with your account,
it's just that you actually only have 3 refs (and 1 of those pending),
one of the actives registered twice, due to the bug i guess, which didn't create a new bcaIN on his first try.
that non-created bcaIN obviously didn't make it to the database and that again results in the wrong display of your stats.
sorry about that, have to hunt that down.
[update]:
this didn't happen for the first time, but it only effected few registrations (~1%) and corresponding ref-stats,
due to the fact, that no bcaIN was created, no coins were sent, received, or lost.
seems like there's a connection-problem from webserver to bitcoin-rpc (which runs on another machine, although in the same LAN) from time to time,
but i don't know why, or what causes it.
i'll see if i can work that out, by adding another checkpoint or something,
else i'll just fire up another webserver on the bitcoin-machine and move the website to it.
i'm sorry for any inconvenience.
