The reason for this is that we dynamically calculate the bounding box of the maps. It was easier than deciding a box for 250 countries manually, and then one for every region and one for every county. It would have been like a million boxes.
Then someone has published the cache GC60D3T which has quite faulty coordinates. It is now archived which will make our maps ignore it in the future. So p0cy just had unlucky timing.
I have started to purge our local data-caches and here the maps looks normal now again. But, due to external data-caching it might take 1-2 weeks before it's proper for everyone.

How can someone think it's a good idea to log it?

Why did the reviewer publish it, note that the location hasn't changed.
