I found another visual bug.
I called this
Shining Effect Visual Bug. All the items who can shine, like Healing Potion+7, Mana Potion+7, Box of Heaven etc. will shine by default if it is the first item listed in the inventory, but if there is no any item in the inventory, the item will shine if it is the first item listed in the one of shops (ex. Lorencia Bar shop).
Another strange thing: a item who can shine, will shine by default when you pick it with the cursor.
Another strange thing: when a Box of Luck will drop on the ground, this will shine (like Box of Heaven) randomly.
Potion of Bless have a damage bug too.@SetecSoft: When will be released a new update with latest bugs fixed?
