Boris K, and I never installed patches 1,3 and 1,4\1,41
so my camera rotates by pressing the buttons :
"Delete" and "Insert" clockwise and back ...
Thanks for the tips. After switching the camera mode, it set itself correctly. It turned out that my camera was rotated by 90 or 270 degrees. I instantly found the 2 rocks I wrote about earlier and dug up the Tear on the first attempt.
I saw other posts where people complained that they couldn't find it. I am 99% sure that the problem is the same as mine — incorrect camera position. When the camera is set correctly, finding it is a matter of minutes.
