Because they didn’t actually live in caves that often.

The image of these people living in caves arises from the fact that caves are where the preponderance of artifacts have been found from European Stone Age cultures. However, this most likely reflects the degree of preservation that caves provide over the millennia, rather than an indication of them being a typical form of shelter. Until the last glacial period, the great majority of humans did not live in caves, as nomadic hunter-gatherer tribes lived in a variety of temporary structures, such as tents[4] and wooden huts (e.g., at Ohalo). A few genuine cave dwellings did exist, however, such as at Mount Carmel in Israel.>

You could post a bug on the Jerboa community. It might be known and have a fix out soon. I think most apps have their own quirks. Either way, let me know if you have any success.

I also don’t get them on Jerboa. What instance are you on? I think that communities wont show up in your instance unless someone has already accessed them. If you search directly for the ones in the post above, they should show up. I think you have to put an exclamation mark in front of the term. E.g.
!weather@community.xy

Hope that works.

Taking a crap (crappers were common toilets back in the day, I actually used a crapper toilet recently, that was a day to remember)

Us Brits offten call the toilet ‘the bog’

Doing a poo is the most frequent in my house.

If anyone thinks their asshole is clean from just a jet of water, they are either eating plenty of fiber or are going around with a dirty asshole. I also have not got the time to blow dry my ass e be every time I poop.
