Whenever I kill a mob, use command @baselvlup the client would just freeze. When i try to relaunch the client, it say's the server "still recognizes last log-in. again after a few minutes." After trying for several times, @go 0 would no longer work, @spawn and even @jump. It seems all GM commands won't work.
I'm just new to the community, and just recently downloaded and followed this tutorial https://rathena.org/board/topic/104452-tutorial-how-to-create-ragnarok-offline-2015-client/as I'm not sure about SVN, but I'm pretty sure I've downloaded the latest version of rathena.
Thanks.
