GP problem

[killabunny]

I'm not much of a rankist, but here's my problem.

This is where it started; Last afternoon, I played a large number of 1 on 1s, winning most of them. Nothing unusual. I logged on later at night, then noticed that I had only gained 30 GP. This was impossible, in my opinion, as I had played a so much and won a decent number of games. The next day, I played again, and this time recorded each game carefully. I played approximately 28 games, and won 23. When I checked later, it had only gone from 15998 GP to 15630!

I decided to investigate deeper. I played a single 1 on 1, and bunged my opponent. I recieved 4 points. I logged out, then back in. 15631. 1 GP in total.

Anyone care to enlighten me on this?

EDIT: Whoops, wrong forum. Can a mod move it please?
