NPCs - double or trouble items selling

[Victor]

Hello. I am using TFS 0.3.5pl1 and him NPC system. In game, when I go my GM to some NPC (for fact there is 1/2/3 NPCs in x-range [windows] and I wana buy in. e. sd (buy 1 sudden death) then NPC sells me one sudden death with 3 shots and getting more than 400~gp (price of 1 sd * 3). The same with Aol-NPC - I wanna buy by trade Amulet of loss, and her sold me 2 aols for 20 x 1cc.

Any1 know some fix?

in the npc... change line:

<parameter key="module_shop" value="(number)" /> to value "0"

if you use the parameter on npc file to sell your items, chance script to "deafult"...
