Is this the right place to post this? Warnings with 6.3.6 on OP_SwapSpell (0x3a19)

I'm seeing a lot of these lines output to the terminal while using ShowEQ 6.3.6:

Code:

---

Warning: Sun 9/17/3206 7:27:40 - OP_SwapSpell  (0x3a19) (dataLen: 13) doesn't match: sizeof(tradeSpellBookSlotsStruct):8

---

The dataLen varies from 11 to 14.

Is this a known problem?

That opcode hasn't been updated lately, and is conflicting with something else. It shouldn't cause any issues other than the warning, but if you want to silence it, you can edit zoneopcodes.xml and replace the opcode for OP_SwapSpell with ffff (which will cause it to be ignored)
