I am running MP 1.3.25 build 1.1.5589.39444
When trying to build a waypoint mission in Colorado (plane is not connected), I add a single waypoint.
My goal after that first waypoint is to add a Loiter command and have it go 4 turns around that waypoint.
Then click 'Add Below', it adds a new waypoint in the southern Atlantic ocean off the west coast of Africa!
It does not matter how many waypoints you do add, as soon as I click 'Add Below' for any one of those waypoints, the new WP gets added in a galaxy far far away.
If I do another 'Add Below' after the last WP, in an attempt to do a 'Return to Launch', same problem. A new waypoint gets added with a huge distance, like this one:
Thanks for reading, and any recommendations.
