Could a more senior user than me please take on the task of fixing the Lake Victoria multipolygon? For the last four or five days something has inverted things so that the lake appears blank and the islands blue. Presumably someone helping out on HOTOSM inadvertently deleted a key relation somewhere, but I can't see where to start looking. It's making editing the region somewhat tricky!
Looks like someone has now corrected it -- thanks if it was you!
