After the icons that show effects that are causing HP loss are no longer present below my Endurance/HP/mana bars, HP still continues to be lost for several seconds afterwards.

When I go to enchant my Primitive Mage Staff, I put in the reagents: Rabbit Paw, Penny Bun Mushrooms, Wolf Teeth, Spider Gland, and Bloodvein. Normally one of the properties is 'Spell Damage Increase'. However, when I put in the 5th reagent, 'Spell Damage Increase' disappears and there are two 'Durable'.

When transferring multiple of the same item from a dead monster onto the slot in my inventory that has the same item, the item is topped off at the maximum of 10/10, but the extras do not start a new stack nor are the extras on the dead monster.
