Try and pull packet info out of source. gamepack 16 and 17 are actually identical, I didn't realize. Interestingly i found if I attempt to map deobbed client that is rebuilt vs the deobbed client, it can't map everything. Some of that might have to do with the packet handling stuff, this currently npes in iinc so I can't tell how many is due to that yet.
