Recently I have been playing around with JOSM to get the hang of editing OpenGeofiction. Most of it seems to be going well, but I have a small issue with two flooded islands.

I built two small islands here: http://opengeofiction.net/#map=17/2.61609/157.35096

A few days ago they showed on the map, but now they are gone. Most likely I did something to flood them, but I can’t figure out what exactly. I’ve searched for some troobleshooting online, but can’t find a reason.

I’m still learning, so maybe (hopefully) there’s a simple solution. Anyone any idea?

Best wishes, Jaap
