New:
You can now add or remove Mobs from the Deep Dark.
(Remove the Settings-File to get the newest configurationa after server start)

You will then find something like this: "skeleton: 1000,5,20"
You need can add new Mobs or remove them (just delete the line)
Make sure there is no typo, or else the plugin will maybe not work.

Adding a new mob could be a Witch;
So you add: "witch: 1000,5,20"

Witches will now spawn after a restart like the default skeletons, zombies etc. but you can also change if there are more zombies etc with the values.
The first value '1000' is the weight of the Mob. (Higher weight => more Spawn-Trys)

The second value is the min-count of mobs that spawn at the same spot.
The last value is the max-count of mobs that spawn at the same spot.


Fix:
Mobs where not able to walk in the Deep Dark because of the recent changes to the SpeedMultiplier from the settings-file.
