I have installed the mod on my nitrado server, edited the config, but the mod don't seem to work. Creeper are still destroying blocks. I tried to use /gamerule mobGrief creeper false and the server said that the gamerule was changed, but same problem. Is there a probelm with Nitrado server's and this mod?

I tried now with a new world and the creeper aren't destroying block's! Not testet with other creatures now.

It's not something I have ever tried.
The mod is driven by Forge events, so in theory as long as nothing is messing with those events the mod should work. Do you have any other mods installed?

I've been intending to add some additional logging for debugging issues such as these so I'll try get round to that so you can at least send me some further info.
