Hi Ticker, sorry, I didn't keep that specific case. If you cannot reproduce I'll try to find it again. Both the triangle and the rest was visited in clockwise order and the start/end was somewhere else on the rest. I think the cut did not go through the triangle but I'm not sure.

Are you sure there isn't a rotation through the connection point, resulting in something like a figure-of-8. Ticker On Mon, 2021-05-31 at 07:41 +0100, svn commit wrote:

Version mkgmap-r4749 was committed by gerd on Mon, 31 May 2021 BRANCH: low-res-opt remove/disable code to merge shapes to the max for now: - hole detection was too simple, sometimes removed outer parts of shapes - ShapeSplitter doesn't handle some degenarated shapes well where parts are connected in a single point, like a triangle connected to a concave shape.

Will try again with a different approach once ShapeSplitter is able to handle these cases.
