Please bare in mind that the maintenance was more of a bandwidth and performance optimization. Now that the game is back up, we can focus solely on the bugs you find! :)
The new server code has introduced a fair load of new bugs. We're really sorry for this, they just don't seem to happen to us when we test it with 2-3 players. We will attempt to fix any bugs you report, so no worries :)
Esgrima is being worked on heavily; All maps including the main city have been optimized greatly, the server code was almost entirely redone, and the last step we are on now is to fix the game freezing bugs. It's worth it guys :)
