Yeah, it happens in 1.14, too (1.14.4 to be more exactly)

It's frustating, in Nether Fortress normal and Wither skellys don't spawn, as well as Magma Cubes and Blazes (yes, they spawn with the spawners), only Zombie Pigman

Besides, I found another Fortress in 1.14 and Wither skellys don't spawn, neither (also normal skellys, Magma Cubes and Blazes)

I built a farm for Wither skellys and since 1.13 doesn´t work. This is a terrible bug, please fix it

(Yeah, I created the world in 1.12.2, I played it in 1.13 and now in 1.14.4)

I did a report (duplicate)
I hope that they will fix this terrible bug, please vote, comment and watch 🙂

(Thanks for the report in 1.4, now it's updated)

Sorry, and thanks for the info (I searched, but I didn't found anything)
