I added an area tagged with natural=water earlier to show the outline of our local river. I was working in JOSM, everything validated when I uploaded and then rendered fine when I checked a few minutes later.

I then added an abandoned farm nearby and now the whole area is rendered as if under water!

I've deleted the natual=water I'd added (and the abandoned farm for good measure) but eveywhere is still blue. Only visible when zoomed in to 13 or more.

I'll happily add more detail but I can't think what is relevant. I'm not even sure it's something I've done but I can't see that anyone else has been working on the area and I don't know where to start trying to fix it other than what I've already done.

You can see the area here

I was working on the stretch of Glynde Reach that runs from the village of Glynde, to the west, until it reaches a dam just to the west of the A27 road.

Cheers

There was a wider problem with the UK being flooded last night and I doubt it was your fault - it seems more likely to have been an issue with the coastline in Scotland. Regardless, it's fixed now.

Happy to accept this answer as it means it wasn't my fault! Thanks for letting me know.

Hi, you certainly did cause a flood. Don't worry though your deletion has resolved the problem, it will take a little while for the area to be re-rendered at all zoom levels. I would suspect that your riverbank area/areas were not closed hence the flooding.

I'm 99% certain the riverbank area was closed as it rendered properly for a while and deleting it didn't seem to help. I've accepted Richard's answer because it absolves me of responsibility!

Non-closed riverbanks just dont render: they never, ever cause flooding. @BCNorwich is just wrong here. Flooding is a problem with the coastline not other water features. This is because coastlines are so long that it is not practicable to treat them as regular polygons, and therefore are a particular special case..
