This mod does nothing but makes spawners think that there's always a player near them. Spawners in unloaded chunks still won't work, however all spawners in loaded/force-loaded (including via ftb-chunks and similar mods) will keep attempts at spawning mobs.
Mob AI ticks are not added. Mob farms with Create are still possible.
This mod is made primarily to be used in upcoming modpack 'omgapack'
