Experience suddenly stopped on blues

[pythag]

I ran a character to level 6 then experience stopped on blue kills or less. I moved to next zone and only some blues and higher give xp.
The only thing that i've changed is I ran this loot sql to adjust loot.

#add defiant drops
insert into lootdrop values (91024, 'Crude Defiant');
insert into lootdrop_entries select 91024, id, 1, 1, 2, 0, 127, 1 from items where name like 'Crude Defiant%' and nodrop = 1; 
insert into loottable_entries select distinct loottable_id, 91024, 1, 50, 1, 0 from npc_types where loottable_id > 0 and level between 0 and 4;

I do have bots but with or without them it makes no difference, I am using rev_2214.
Not sure where to look on this and I wouldnt have thought the sql would alter the xp given?
