(Fixed) Mine control tower: UI issue - Export routes

Screenshot #1: Tower with 3 export routes. All OK
Screenshot #2: Tower next to the first one. UI shows the very same exports, which is not OK.
Also, it is impossible to delete export routes from the second tower UI by right-click.

Additional info:

1. Save re-load don't fix the issue - another tower's routes can be displayed for both.
2. If I remove or add any of Export route to any of these towers, then the issue gone. The issue occurs only if these both towers have the same amount of export routes (tested with 2 and 3).
3. Red arrows shows correct routes
4. The actual rules are correct - trucks deliver the cargo to the correct locations
5. Towers have been copy-pasted originally
6. Save game attached

Can you try to add one more route manually? I think it can be connected directly

The fix is click the tower then click the export location to remove it from the list

Looks to be fixed in b431 (experimental)
