Cannot craft anything anymore. Examples:
Item in hand
If i keep an item in hands, i.e. hatchet. I drag a can of food, a long stick, a piece of clothing, on the "combine" box and i get the RED highlight.
If i try to equip an hatchet, set a can of food in my hot bar, keep the hot key pressed wont prompt the "open food" action.
Item on ground
If i keep an hatchet and set the aim on a cloth, a can of food, a stick, i no longer receive the crafting option.
Side note, sometimes picking items up is not responding, either by dragging in hands or by "hit f to take in hands". Hit F usually works after 2 or 3 attempts.
