v144.3 Enter Portal Packet

Hi guys!

I was analyzing 144.3 packets, and I stumbled upon an unknown int within the Enter Portal Packet (when you press up on a normal portal)

First of all, a sample packet is this:
Code:

51 00 1C FF FF FF FF 77 88 EE DA 06 00 65 61 73 74 30 30 EF 00 B1 05 00 00 00
Breakdown:
Code:

51 00 - header
1C - Portal session ID (increments by 1)
FF FF FF FF - Some constant
77 88 EE DA - Unknown, changes every channel change (probably CS too, didn't check).
06 00 65 61 73 74 30 30 - Maple String (portal name)
EF 00 - X
B1 05 - Y
00 00 00 - some toggle stuff

So the 77 88 EE DA part.
I figured out the it changes quite randomly every channel change. Of course, putting in random bytes to replace this won't execute the script. I assume it's within some packet that I receive when I change channels, but I can't find it. (I pretty much Ctrl+F'd 77 88 EE DA in packets I received after channel change. Googling gave me older breakdowns, which claimed this part was constant (so I assume it was added last year on).

I might just be asking a very easy question, but nevertheless, does anyone have any ideas on the int that randomly changes?

Thanks in advance!
