I finished the Ankeveense Plassen top multipolygon for the fourth time and now it looks like it's going to stick in both render engines. In osmarender the whole thing is complete and in mapnik I'm waiting on the last few islands to show up next wednesday.

I now also moved some of my attention to the Naardermeer, a lake NNE of the Ankeveense Plassen. A lot of the lake's shores are in dire need of correcting and islands have to be created. You'll see now a nice difference between osmarender and mapnik which showes exactly what I've done so far.
