spawners giving mcmmo xp

if you have way too many spawners like deo, and you get thousands of mobs, some get stack but become immune to cramming, when they get unstacked and drop down in the farm they will give mcmmo xp like they were naturally spawned, this is high priority as it gives big chunks of xp really fast
