no mobs spawn for me in the nether only blazes from spawners nothing else spawns for me

just tried making a darkroom spawner in the overworld and nothing is spawning in there either im in normal mode and i cant advance without pigmen

Darkrooms in the overworld will not spawn mobs. Mobs should be spawning in the nether, though. Might take a day or two before the devs can check this out.

Mobs will spawn from spawners and cursed earth. They SHOULD spawn naturally in the nether. They WILL NOT spawn naturally in the overworld. It's only been 2 hours since you reported the bug, and the devs will need to look to find out why they are NOT naturally spawning in the nether.

well ive made multiple worlds and all of them no mobs spawned

Are mobs still spawning from spawners though?

yes in every single world

im not expecting an immidiate solution just trying to help by reporting bugs i find

I have an idea what's causing that. Probably something with the game rules I set when a new world is created.
