That is most common error when you are editing packet.h without really understanding what are you doing ? My advice for you is fully compare packet.h from binary+game they must be same..
check for duplicates, check if you dont have something // in game but dont in binary, check if every packet is defined in right way in (PythonNetworkStreamPhaseGame/Item.cpp)
ex. if this packet in binary = 80 it has to be 80 in game too
HEADER_CG_GUILD = 80,
as last that = 80 must be unique so you cant use it for another packet, but be carefull there are 2 types of headers CG and GC (if you use 80 in CG packets you are free to use same number in GC but you cant use same number in 1 type of packets)
ex. WRONG
HEADER_CG_GUILD = 80,
HEADER_CG_WHEEL_DESTINY = 80,
I hope this will helps, if it dont, insert here your packet.h files I will look at it ?
