My problem Like the title says it below... I try to use the client 2013-08-07 with which I used ./configure --enable-packetver=20130807 to compile. I also used git clone https://github.com/rathena/rathena.git ~/rAthena which means I use the latest rAthena revision. But now everytime I try to log on my character I get both these errors on the map server: [Warning]: clif_parse: Received unsupported packet (packet 0x7f57, 19 bytes received), disconnecting session #8. [Warning]: clif_parse: It looks like you have enabled PACKET_OBFUSCATION on server side, but disabled it on client side. I fixed the problem by disabling packet obfuscation, but clearly I'll have to make a new client.
