Error in map river generation

[Winterbottom]

I'm getting errors, as in the title of the topic. No mods at all. It only happens in one specific place I found so far (un-lucky me) at a specific size (the second medium size, the standard one is okay). As super specific as it seems, I think it might be worth investigating?

The logs are taken straight from a fresh uninstall game, with config file dumped, then reinstalled and headed straight into the world creator with these exact settings.

Looks likely to be legit, maybe a rare river generation bug. Here's the first few lines.

Fixed, thanks.
