Strange shape of Israel-Egypt border

Hi all,

does anyone know why the Egypt-Israel border shows a curious circular bend at certain zoom levels. I tried to fix it but couldn’t find anything to edit. See here (the area in question is about half way between Eilat and Gaza):


It was probably mapped with a strange circle for some reason, I don’t know why.
I think it had been corrected quite a while ago, its just the map hadn’t been rerendered at some zoom levels.
I’ve now marked those tiles as dirty, which made them be rendered, the border now looks correct.

Perfect, now it seems to be correct. Thank you.
