Just FYI.. it's great that you guys are actively updating the numbers and such, but honestly it's a waste of your time. I've had mine set like the below for longer than I can remember and haven't had to update the file a single time since then.
LNKPD_MAX_ITEM_ID = 110000;
LNKPD_MAX_SPELL_ID = 150000;
The addon does not bug out if you provide a number higher than what's actually available. After a big patch or expansion comes out you might want to bump it up by 10 or 20 thousand each, but other than that the only thing you need to do every once in awhile is rebuild or rescan. Poof, done.
Hope that helps.. again, not knocking the people being helpful, just saying you don't need to waste your time with incremental updates like that.
