Item made by tinkering craft named "Knockoff Royal Banquest Candle" can't be traded/bartered. Once character put this item in barter menu - item dissapears and character makes animation what it puts candle on ground.
It is issue because this candle marked as prestige item.
Suggestion - simple make it as tourch with model of candle. Not as actual candle.
Candle disappears even when it is just dropped on ground.
This is almost certainly true of the non-knockoff version also. I tried putting it into a container placable once and it vanished. I think it's trying to "activate" and become a candle placable. Not sure.
Same thing happened with a real Royal Candle from The Dispensary.
