Do you realise the green cross represents the roots of the fallen tree? That is where the control should be placed, not half way along the trunk.
To JohnT4: I took my only course setting class 52 years ago - don't remember rules like this :) The real reason is that map upload size (10 MB) restricts map area and you have to make solutions like this: you either forget some rules or don't make any courses.
