three issues, that i'm 90% sure are bugs. for context, i'm on an easy difficulty world.

one: blaze knockback seems to be WAAAY higher than normal. I got sent 3 entire blocks back. a sword don't even do that! or an explosion! (because you die)

two: ABSURD amount of mobs. I had 35 wither skeletons chasing me, as well as 3 blazes. in the overworld, even in GIANT caves, I wont see more than 3 zombies. this is ONLY a problem in the nether for some reason. the end? fine. they spawn in large groups, and REAAALLLLY fast. I had two 10 piglin hunting parties spawn within half a minute of each other.

three: blazes naturally spawning across the fortress. I have cleared every spawner, but blazes are spawning at random places in the fortress. some even spawn far away from the fortress. and they are spawning. my render distance is pretty good, so I know when a blaze spawns 5 blocks in front of me.

I cannot even get nether wart.

forgot to mention: this is ONLY a problem in the nether. these bugs don't effect anything else, but I can't progress because of it. and I'm on easy difficulty. I don't know how long this has been a problem, as this was my first time finding a nether fortress.
