The RemoveDuplicates command appears at the top of CustomUI scripts screen.
As of MoI4, it removes duplicate points as well as duplicate curves...
The RemoveDuplicates script appears in the MoI4 or MoI5beta commands folder, not in AppData commands folder.

I may be mistaken, but other than CustomUI, MoI does not have a way to see these "extra" commands, like Flip, Make2D, Merge, Rebuild, RemoveDuplicates, etc.


Michael's SelectDuplicates script also finds duplicates, and can allow the user to delete the found duplicates as well.
And it has a tolerance.

I just added it to my add-on scripts in AppData.
I suppose that it could be added to the top of CustomUI scripts screen...
