Good, thanks. Please let me know if you do get something.
If the new bytes are used, I'd expect them to be used in new content somehow. This wasn't really a content heavy update, and the only things I see as options that use the action packet are:
1) Fishing, new system or possibly specific to the new rods.
2) New pets / New Blue Magic - Very unlikely, as none of them involve new mechanics
3) /sitchair might be an action? There's no reason for it to require more bytes, though.
4) The new /bstpet text command. This one also seems unlikely, as it could be entirely handled client-side and just send out the same packet.
5) Could just be in preparation for the future.
