whenever i try to duel someone who's in event , i see 'server:unknown command'

It's not a bug. About that message, it's because the command could not be completed as to prevent players requesting duel to other players that are in event. And while there is no specific message set, the "SERVER:Unknown command" message is sent instead. I believe this is what happened in here.

There was a small bug in the code. It is now fixed in the next update (v4.2.6).

Thanks for reporting it.
