[mkgmap-dev] Bad tile around East London / Greenwich

Hi all, since some time my map has a bad tile around East London (Greenwich). I´ve checked earlier revisions of splitter and mkgmap, and decreased splitter´s max-nodes - without success. Problem seems to be in my style, which is based on OpenFietsMap. With the original OFM-style the error is rendered as well, but not with the mkgmap default style. But I´ve got no clue where to look for the mistake - anyone has got a hint for me? https://files.mkgmap.org.uk/download/516/bad_tile-east_london.jpg Jan
