Multipolygon turned white
[Cross-post as it does not get through on Forum]
Please help, I seem to have run myself into trouble.
I have been editing a lot (in the ID-editor) on [Koudenhoorn][1].
The base is formed by a scrub multipolygon, containing a lot of inner relations.
I follow the result more or less in a separate web-browser, restarting to clear the cache. Information Freeway. At some point after editing, that base turned all white (viewing on a scale which represents the latest state best). At first I thought it was just a matter of lagging, but it seems to be a structural problem.
I have reinspected the map, also tried Potlach and JOSM. I don't see anything clearly wrong. But I fear the problem is caused by the polygons, which are already pretty complicated. A clue may be that in the ID-editor marking of some edges seems to be 'jumpy' (double or alternating).
Do you have suggestions what may be the cause, recognizing this problem?
Or would you please have a look at the map, identifying some error?
I don't want to end up messing up a map, after thinking to have improved it a lot. I hope I can just clear some error.
Thanks!
