Hey everyone! I love forge, and I love minecraft and have been doing it for 2 years now.

 

So basically, I was trying out new mods for me and my friend's server, and I suggested ars magica.

 

It took up waaaay too much CPU, and I had to remove it. Now when I start the server, I end up with the following error.

End of edit

Try making a new world.

That's not possible. I've tried re-making the overworld, but it's got something to do with a mystcraft age...

 

I don't know which one, and I don't wanna delete our worlds.

 

Are there no other workarounds?

Here i know one:

 

1. move your world

2. make a new world

 

THAT EASY? Also you don't delete your world!

What do you mean make a new one? I've literally played on this very Age since 1.3. I don't wish to delete it, I would like to delete all entities in that specific age. Don't even mention MCEdit, it removes all non-vanilla blocks.

This is interesting probably an issue with a entity having a special effect from the ars magic mod. What i'd do is r-install ars, set your world to peaceful. And then run to the location specified by the exception and kill the mob.

 

Hell, setting the world to peaceful should help as its a skeleton and it should kill it on its next tick.

I've tried to put it to peaceful already, didn't work, I'll reinstall ars then...
