Meadow Biome rather rare?

[ಠ_ಠ Uhuu]

On my first world seed I had everything on Normal and had no meadow Biome in the starter Ring
My second world seed i started also had no meadow.
I started a second world with:
Biome Chaos - Extreme (never gonna do that again, super annoying map^^")
Ore, Tunnels, Chambers - High
River, Lakes - Normal
Pits - low
Ceiling holes - high

Anything preferable to have high chance of meadow biome spawn?

Only way that happen for Meadow Biome not showing up is by setting Biome Chaos to none.
In your first world. You probably going have to go nuts on breaking walls by using a hammer like I do to find it on your first world.

When ever I find those Meadow Biome. It always have a meadow block around it and stop other monster from entering Meadow Biome. I only find them in dirt biome and forest biome(it actually call Azeos' Wilderness).

You probably higher chance of finding it by setting to

Biome Chaos - normal
Ore, Chambers - any(don't really matter)
River, Lakes, Ocean, Tunnels - none
Pits - none
Ceiling holes - Extreme

How ever you more likely run into monster this way.
