I edited several areas fixing the coastline a while ago. I first fixed the coastline here to make it not look jagged. That was over two months ago, but it still hasn't been re-rendered. I know it was saved because the coastline doesn't look jagged when you go and edit.
This is not the only place where this is going on. Nearby, I edited another bit of coastline that was inaccurate. See what I'm talking about here. West of the marina, the coastline is supposed to follow the purple dotted line, but the renderer has failed to update this coastline which I edited more than a month ago. Again, it is where it's supposed to be when you look at the data layer, and in Potlatch.
But wait, there's more! I edited another bit of coastline 3 weeks ago (Jan. 14) to make it not look like there were a bunch of roads floating on the water, as shown here. Still hasn't updated.
I put in a render request on http://www.informationfreeway.org a few days ago, but I don't think that helped at all. I even edited the coastline a bit just to see if that would get the renderer to do its job. If either of those things worked, I'd not be posting here. Has anyone else had this problem or do OSM's servers just hate me? Someone please fix this, because this is unacceptable and should not be happening.
Attention programmers: I have zero programming experience, otherwise I would have never posted this and fixed this myself. So please no "fix it yourself" comments. Thanks!
