If a character buys all of a particular item, then the vendor will not restock it.
I logged in with the admin account, bought all except one of a particular item, then used the 'restock command to force a restock. The vendor restocked as they should.
I then bought all of the items so they had 0 left and used the 'restock command and they do not restock the item any more.
I am using the Default UOX3 Worldfiles 0.10 and community made spawn files. I have not modified any of them except for adding a few additional creature spawns around Yew, so I haven't touched the vendor lists and item lists.
Anyone else have this problem or do I need to set something in one of the settings files?
