On our server I have the config settings for the Magical Predators set to all 0, but almost all of the time when I log back into the game 1 or more spawn in and kill my Minecolonies villagers and then they kill me with the crappy un-removable instakill energy balls they leave behind. We originally removed them because they don't obey the light level restrictions that mobs ought to follow in minecraft and had a very high power level, as well as the instakill balls. Now we're going to remove the entire mod because they're not listening to your own config settings. Shame about a very cool mod - not sure why you felt it necessary to add these to this mod or to implement them as they are.

We do not recommend using an earlier version of the mod on servers. It is in early access and does not work correctly. The update of magical predators will not be soon. They were originally planned as complex enemies with different life rules, but the incorrect operation of the config file was not planned. Show us your config file so we can figure out exactly what the problem is.

It could well be some conflict between mods - other people were also having issues, mostly around them spawning during the day, but what i was seeing personally was that a lot of times when I logged on 1 or 2 of them would spawn in the same location in my Minecolonies village. I never saw one spawn any other time.
