Unknown Packets

Unknown Packet <switch>

Only happens with version 2.0.7 or preceding.

Tokenizer: Unknown Lengths

Packet Tokenizer: Unknown switch: <switch>

Packet switch is not found in recvpackets.txt, so packet length isn't known. There's a chance of getting desynced game state (undying monsters, inventory glitches, missing skills). Recvpackets needs to be updated for your server.
