It seems the stats have been reset for Wild Fortress and Catfight.
What caused it?
My best guess is that when the server ran out of space (literally not a byte to spare), it tried to get extra space from somewhere to write it's log files to. Since the stats are variable files, it took the space it needed from them.
Dogfight was spared since noone played there during the time the server ran out of space.

Look on the bright side, it's a fresh start for everyone.
And before you ask, no, we can't get them back.

Also, thanks wrtlprnft for linking the stats from Chico's Brake Boost Styball. These are now online.

would that be why its been so laggy for me lately?

It's been lagging for you lately because the stats have been reset?

Maybe I didn't word it correctly. I ran out of disk quota. My allocated disk space. The server itself didn't run out. This should not have affected performance.

Could have caused lags if the server was trying to fill every last byte on the partition, and arma was waiting to write something to disk.
It should all be back to normal now.

If I was °°° 3dot °°° I would be super pissed

i bet 3dot's not too mad he doesn't seam to care about stats.
I'm glad i can start fresh with my new name Z3|

i really don't care, but maybe the version change can be a cause?

Nah, it worked for ages after the change. I even backed up the stats (and deleted them after I saw that they still worked)…
