#804

This is the Ticket I made the other day, but it was my fault for blaming it on Worldguard... But its because the Shopkeepers I had at spawn had NBT tagged Items.

Such as Custom Items, Vanilla Potions etc. <- works fine if its just plain items

Sorry if this has already been addressed.

I already had users report that they were able to reproduce their specific ViaVersion issue without custom items being involved.
I updated the Known Issue on ViaVersion again to clarify that some issue seems to only affect modified items, whereas other issues may also be reproducable without any special items.
