I've been trying to learn 2.8 but I ran into stupid issue. I have nothing selected and (in object mode) I try to (shift-a) add a plane, cube or anything and it is added but it is not visible and I can't find it. It is not in any collection as far as I know. I can't enter edit mode and pressing "," doesn't find it either but it is selected as its properties are open on the right side menu (Plane.007 and so forth...). If I add object while having other object selected the new object appears normally (as the new object is added to new collection). Where is it?
