Kartographer associates incremental POI according to their position inside the wikicode, but in it:voy we use some LUA templates that alphabetically order their content.
What we need is to implement the same LUA sort function inside Kartographer, to be used everytime those template are called otherwise there is a discrepancy between the POI numbers inside the article and the POI numbers shown in the map
UPDATE: After several years of no support, I've changed the old templates logic. We'll live without the sorting feature.
PS I've declined my ticket.
