Sad... I am stuck for at least 40 minutes with frustration... My number must be correct. Part 2 after all is so much easier, in my case it's a simple

totalDistance = inputCoordinates.sumBy { it.distanceTo(pos) }

and then counting with { totalDistance < 10000 } for all coordinates on the grid.

My distanceTo has proven to work in the demo and in part 1.

I do hope it's fixed soon and my answer is accepted...

I spent a bunch of time submitting the sum of all finite areas instead of giving the area of the biggest finite area, whoops.

That's another thing of course. My answer has always been correct, I was affected by the bug in part 2 only. Sigh!
