New:
There are now new settings for decoration-features (fossils,dripstone,vines, monsterrooms, geodes...)
A high number will spawn those features multiple times.
(Thats why monster rooms have a 10, geodes/spore_blossom 25)
If you set the number to 0 or negative, the decoration-feature will not spawn.
!!!
You will need to restart the server completly to make this effects work
