Looks like a mesh problem and some elevation issues. I face the same problem on SU3 and it is frustrating tbh. I know that these things might occur because of the FS updates having so many changes pretty often 😛
Hello,
Lately I have been having trouble with the lines drawn for the approach. This happens at LWSK [Skopje]. Everytime I choose the approach it draws some strange lines between two waypoints and makes you fly around mountains with a low flight level. That lead you to directly crashing into the mountains.
