| Rates |
chance: 70
max_height: 40
min_height: 20

This can be altered in blocks.yml

-IMPORTANT-
Dont want blocks to be spawners?

There is only so many mushroom blocks avalible.
To combat this these blocks are pretty much spawners that spawn armor stands holding blocks.

You can change this by changing the following values in blocks.yml


placed_model:
type: TILE

Into


placed_model:
type: REAL

Keep in mind there is only a max of 191 blocks in total

You can check how many you have left on your server using /iazip and checking console for

Used ??/191 REAL block IDs.

And picking and choosing what blocks you would like to be REAL blocks.

This is the only suggestion I can make for fixing this problem.
