Problem with global loot

[lymontyme]

I have a rather long streak of crickets chirping when I post, hopefully this won't continue it...

I'm trying to enable global loot so that every non-skipping mob has a 50% chance of dropping a lamp with red tinsel (item 59444). So far, no luck. Can anyone spot the problem(s) below? Here are the records I added, with notes on trivial fields:

global_loot:
id,description,loottable_id,enabled,min_level,max_ level,min_expansion,max_expansion
21,STUFF,200000,1,0,100,-1,15 (all other values null)

lootdrop:
id,name,min_expansion,max_expansion
200000,STUFF,-1,-1 (all other values null)

lootdrop_entries:
lootdrop_id,item_id,item_charges,equip_item,chance ,disabled_chance,multiplier
200000,59444,1,0,50,0,1 (all "level" fields set to 0)

loottable:
id,name,avgcoin,done
200000,200000_STUFF,0,1
(cash set to 0, expansions to -1, flags to null)
(I have no idea what "done" does, neither 0/1 work)

loottable_entries:
loottable_id,lootdrop_id,multiplier,droplimit,mind rop,probability
200000,200000,1,6,0,100
