As far as I read, it seems that the catchup system is still not fixed. Warmane should start getting serious about it since it seems that the server population keeps dropping (idk, I haven't played for a while... in part because of this bug (not because it would benefit to me since it wouldn't at all, but to the server itself)).
I'll keep an eye on forum from time to time to be aware of its catchup system status, checking the population, and eventually coming back for some matches (when my other reasons let me XD).
Greetings!
