Windows 10, Java latest version at the time of release So I linked two nether portals from my base and to a zombie spawner I found. The portals are not very far apart in the nether. I was building some stuff in the zombie spawner when suddenly I noticed a HUGE lag spike, like so huge I didn't know where it came from. I thought it was just the world trying to load or something so I reloaded my world, twice. Anyways, when I realized this didn't do anything I tried to go to my base and that's when I noticed a freakton of zombie- pigmen at my nether portal. I immediately tried the /kill command and went through. I saw the same exact thing back at my nether portal in the overworld but nothing in the nether. Please help I can't currently do anything right now with my world.    P.S: I can still move fine and evrything but when I break a block it's really laggy and so are the entities.
