LoadSpellSet_Struct now uses bytes for each spell slot and uses 0 to leave alone and 1 to unmem that slot. Total length of packet received is 16 bytes.
Code:

Is underfoot a max of 10 spell gems or 12? I saw it say 10 in Underfoot_structs.h but UI files I have seen imply 12 gems. If it is 12 gems, then they simply changed from DWORD to CHAR for each value and then changed from 0xFFFFFFFF to 0x0 to not unmem the spell.
