the place appears to be defined in iNat as a single point. i’m not sure i would call this a bug exactly. the place just needs to be properly defined with polygon geometry. you could probably just flag the place and work with a curator to fix it.
I get the error as described by @earthknight if I type “Big Bear Lake” into the “Search” box at the top left of the home page (and then selecting the fourth option, which looks like it’s going to be the location Big Bear Lake in CA, USA), but the correct location if I type it into the “Location” box after hitting Explore.
