I've been in-active in OTs for some months so excuse me.. But alot of NPC stopped working (used TFS 0.2 before).
ADDON npc and other NPCs that trades ITEMS for ITEMS/addons. (Normal npcs that you pay money to works fine.)
Is there anything that I need to change/upgrade?
Sorry body i have never use a npc that trade items for addons :S
to me that kind of npcs are useless to me :S
It's not only the addon NPC.
All NPCs that trade ITEMS for ITEMS are bugged.
I get no error in the console, but the NPC just ignores me when you're going to buy an item.
