I posted this in the comments for the plugin but you can quote me and I'll get notifications here blainicus - is there a specific issue you're having with defining mob AI? I'm interested in this and might be able to throw some resources your direction to get the super aggro fixed on everything again. I'm also having issues with getting spiders to burn in sunlight, works fine on endermen but not them. I enabled the other monster properties setting. Lastly, it seems ONLY spiders have mega aggro, not creepers or endermen either. Thanks!
