+====== Combine Road Features ======
+USA Los Angels 40km terrain openstreetmap.org road polylines even after "bad roads" reduction were over 17,000 features which is like ten thousand over the limit. They need to be reduced. Please note that this was some very odd issue on these specific OSM shapes because normal roads / streets were split up to hundreds of small features when it should have been one feature.
+I have not experienced such splitting up of polylines in other terrains in this scale.
+Select all roads -> RMB in the viewport -> crop/combine/split functions -> combine. Then use about 6 meter value, should work fine (we used also 20m but that might be too large). In select combine options menu let it be default (combine any overlapping and everything else ticked).
