World crashes after too many mobs spawning through eggs

Somebody kept spawning too many villagers in my world and I accidentally force quit. When I came back the world keeps crashing to this day. Now before you mods say anything about it, this bug is NOT a duplicate of MCPE-10644!!! The villagers have been spawned through SPAWN EGGS, not breeding. Plus, I keep CRASHING, not substantially lagging. As such this is not villager breeding, this is villager EGG SPAWNING. Please help me because we're gonna get in a lot of trouble if you don't fix this.
