Apparently I have a phantom object, but it is not that it disappears, but the object that I picked up (bell), I stay in the inventory, when I select it it flashes on my mouse and returns to its place, I press Q to throw it and it does not nothing. Also when I grab another object and try to change it, the object disappears until I open and close the inventory 2 times.

I tried to break the place where I looked for it, I backed up and nothing happened (Previously it had happened to me and I solved it that way).

This causes me to have a less place in my inventory and some objects disappear and have to open the inventory several times.

Sorry for the English, but use the translator
