Unable to generate a valid starting location Desert Island

[moxian]

Describe the bug

Started a new game in Helicopter Crash scenario. Got the error (see below). After pressing a button, got shoved back into main menu.

Unable to generate a valid starting location Desert Island
[sloc_desert_island] in a radius of 3 overmaps, please report this failure.

Nothing of interest in the debug.log

Not sure how this report is useful to whoever put that error handling in place.

Probably unsurprisingly, the world did get created, but not the character. Attaching just in case that's useful.

Trying to start new helicopter crash scenario after the error worked just fine (both with random location, and also specifically with desert island one

Dupe of #35376.

Desert islands are rare. World gen settings can make them practically non-existent. That bug is there to prevent endless searches, among other things.
