I haven't dug through a raw decoded packet, but judging from the XP value display in SEQ (4.0) did Verant change the format of the EXP values in the packet?
Currently it's showing that I have approximately 3.8BILLION experience points. What's interesting is it looks like a structure problem because the value SEQ displays subtracted from 2^32 is within the range of the amount of XP (raw value) I should have.
