Hi Ticker, okay, no problem, I'll work on the faster-mp branch in the mean time Maybe I'll merge it first into the low-res-opt branch.

I'm having trouble reconciling it with the OSM map. I've attached the original shape trace. I agree that some of the messages do need tweaking, but, in this cases there is a significant problem. I'll consider the types of messages etc in the new version I'm working on. I'm away for a few days and won't be able to do much remotely.

Hi Ticker,
please check https://files.mkgmap.org.uk/download/512/63240024.o5m with (unpatched) r4756 and these options --generate -sea=multipolygon,floodblocker --preserve-element-order --order-by -decreasing-area --allow-reverse-merge
Produces an error message SCHWERWIEGEND (ShapeSplitter): e:\osm_out_work\norway\20210511_095323\63240024.o5m: Vertical split 36691968 failed on shape at http://www.openstreetmap.org/?mlat=65.979056&mlon=12.308790&zoom=17 P ossibly a self-intersecting polygon for this invalid multipolygon : https://www.openstreetmap.org/relation/5294624
The result doesn't look wrong, so I think there should either be no error message or we need code to remove those self-intersections or ignore invalid MP like that?
