i would recommend read this https://adrenalinebot.com/en/api/example/packetunit-ready-unit-working-packets-adrenaline-bot because how u read seems not right.
p2 should contain (in my case MessageID), Size, Type, and values by Type.
thats why i dont have answer for ur question in this case, because ur system message data seems odd to me xd
ps. u always can use move and check if u moved.
