Where are objects if you add them when nothing is selected? 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?
Turns out blender has new feature that allows you to disable objects in viewport. For some reason all my collections except one object were disabled in viewport. Turning them back on made the objects visible once again.
