It is normal for all SoF+ clients to send shifted slot IDs for all slots over slot 21, since Power Source replaced the Titanium Ammo slot and bumped them all up by 1. This is all handled directly in the <patch>.cpp files near the top such as in this file for SoD:
http://code.google.com/p/projecteqem...atches/SoD.cpp
I made slot converting functions that adjusts Titanium slots to later clients slots and visa versa.
So, even though you see it sending slot 30 (cursor slot in Titanium), when it is in slot 29, it is actually converted back to slot 29 before it is actually handled in any way.
If something is making it into the handling without being converted, it is most likely due to us missing an encode/decode in that .cpp file for that particular packet type. It is pretty easy to add encodes/decodes if needed, we just need to know which packet it is that isn't in there already.
