New error after fixing regional_settings.json

[PanicPanel]

Can still play the game but I'm not sure if this will cause any problems down the road.

I was getting this too. I think it's somehow related to "mon_bear" tag. It no longer happens after I moved the definition of "mon_bear" above the "mon_bear_cub" one in \data\json\monsters\mammal.json in the main cdda folder,

I'm not familiar enough with the code structure to understand why that works. The PK mod seems to add new bears by copying "mon_bear" in the monsters\misc.json
