Oh no, that is definitely a bug. I tried to make it so that basically everything would be same for everyone as much as possible. I guess the drawing of different hand size messes it up somehow. And that is indeed pretty much how I'm doing it.
There is a rule for checking where those spots can spawn making sure that they don't cut off portions of the map and if I remember correctly, it also doesn't allow any of the start tile surrounding tiles to be one. So that could be the explanation for this level at least.
