The log mentions this: <li Class="OpenTheWindows.StatPart_Landscape" />

That's XML which does not exist in this mod. It must be some other mod that's trying to patch into Windows, presumably the BO like you mentioned. Wasn't aware they were doing patching on their end.

Anyways, the "StatPart_Landscape" stat it speaks of no longer exists. It hasn't worked in a very long time now (basically just orphan code) so it has been removed from the code with this cleanup.

As such the integration with that mod also hasn't been working since 1.4 either (and by some extension the 1.3 version was reportedly not fully working either). All of that just needs to be rewritten from scratch one day.

Ran into the same problem here. I noticed that the intended beauty calculation no longer works, which isn't a huge deal, but it's still a fun little thing I appreciated in previous versions.

Do you have any timeline for when there'll be a fix, or is a low-priority kind of deal? In any case, I appreciate the hard work you put into modding!
