I've searched for chests and nether warts in 4 fortresses, but I cannot find even one.

1.16 is nether update and I know there'll be some bugs in it.

If we cannot get warts, we brewing is impossible. And without chests, players may not want to go to fortress----they go there for blaze rods, for brewing, for chests, for wither skeletons' heads. But there's no wart to brew, no chests to be found. And without brewing, it's quite hard to beat the wither. There're only Wither Skeletons, blaze, it'll be a dangerous place.

I hope this bug will be fixed soon.
