NPC Spawning Issue?

Game mode: [Online | Singleplayer]
Problem: [Crash | Bug | Performance | Misc]
Region: [Here]

I’m not sure if this is a bug or not but this morning while playing on official 2808 I started noticing some changes. Things like monster combat being changed, not attacking within its usual loop, attacking much faster than normal. And then things started getting weird. Everywhere I went the monsters were spawned in 3s. Everywhere, you should have seen the mobs of shell backs, 9 of them all around a nest, every croc accompanied by 2 more. Is anyone else seeing this? Is it a big? They are all inside of each other and then separate when they aggro.

Steps on how to reproduce issue:
1.walk around
2.find a croc
3.oh that’s three crocs
