I've encountered almost 0 bugs with the new wastelanders update after a few hours of playing. There’s only one bug that I've encountered which has almost made my entire experience with wastelanders unsavory. I call it the proximity respawn bug. This bug has been around since around patch 13 from what I remember.
Here's what happens: If you die and respawn too close to your corpse or point of death, to the point where it wouldn't require a loading screen that has your photos but rather a black loading screen with the white animated loading icon, then you will be kicked back to the map and be told to fast travel.
If you exit out of the map screen, it will tell you to respawn.
There is only one way to get around this bug, which is to fast travel or respawn (depending on if you clicked respawn already) far enough away from your death point, this will respawn you as normally.
This has been tested on both private and public servers, with the severity and frequency increased on the public servers.
Everything else has been spectacular though, I'm excited to keep playing but hesitant to die
