W3GS_REQJOIN has proved to be inaccurately documented in 1.29
https://bnetdocs.org/packet/446/w3gs-reqjoin
it is 1 byte more in 1.29
and I found what it is: wrong documentation
the (UINT32) Unknown they describe is not fixed-length
A client sends this to the host to enter the game lobby.
so, (UINT32) Unknown is  2 bytes in 1.29 if he is to be believed, maybe that will give a hint to what this unknown is
