In previous versions the packet IDs changed and had to be updated. But I'm feeling it's something different this time, but I hadn't had the time to look at it myself for now. If I find something before it gets officially updated or someone posts a fix I'll let you know.
If you want to take a look at yourself, try to understand the chain of functions the program runs through from getting a new packet to triggering the onServerPacket function in the scripts. The function is never triggered anymore, find out why ;D
