In order to recreate this bug:
- Establish a looped carrier path
- Once the loop is established, save and close the carrier menu
- Reopen the waypoint editing menu for that carrier
- Use the minus button to remove the last part of the route
- Click the “X” button to close the waypoint editing menu WITHOUT SAVING
Once this process has been completed, the original route will be intact but the looping will have been disabled by the bug.
