Just started a new game on the newly released 1.19-rc4 to have a look at all the new features. Playing vanilla, small changes to the land mass and upheaval values, rest unchanged.
I spawned on an island no larger than 90 x 200 blocks and I'm shocked to see what I find on this small island Very sparse vegetation, only 2 adult trees on the entire island, rest is shrubbery and grass. 1 cranberry bush is all that I've found worth of easy food. There are 3-4 small, strange ruins scattered around where the trader is located, 1 of witch had 1 forage vessel with some clay.
I spawned with a flock of 4 wolves, with a black bear roaming right behind them to my right, and on my left side I have another black bear. As I always play survival, this got real busy quickly, and I managed to escape with all my hp, somehow..
To make matters worse, as I make my way towards the trader who's also stuck on this small piece of land, I find another flock of 4 wolves, followed by yet another black bear not far from them.
I circle around them to speak to the trader, just to find yet ANOTHER bear, brown this time, resting on top of a small mound not far from the trader carriage.
To accompany us all, we are also blessed with 8-10 rabbits, 1 moose mother and 3 calves, 1 fox and 2 racoons...
There's got to be something wrong with the spawnrates of bears and wolves!
