Problems with OnUseNPC

Hi, we have a problem, if I only put one NPC with a shop, then everything works, but with a second NPC that has a different shop, there are problems, but shops with items are available for every NPC

Failed to call hook 'OnUseNPC' on plugin 'Shop v1.2.14' (ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index)

And here is the config for it

Shop.json

Hi! I think you forgot to give players permission ("shop.pizza" or "shop.blackmarket")

Oh yes, I'm an idiot ^^

Can already say the error message is no longer displayed and with -1 (1.2.15+) in the price to hide is also possible.

I noticed, especially when it comes to the same basic items (other skins etc.) there are sometimes problems when opening the editing (the first item of the basic item is called up), here there might be a statement from ItemID when opening, SkinID, DisplayName/Title and Category a sensible way to use it.

Here are a few more suggestions:
- Permission to execute the chat command would be good (if you want to do this purely via NPC's)

Please close
