So ive had a singleplayer survival world (with cheats enabled) for a few days. Enough to build up a fair bit of progress. Anyway, i load up my world one today and find that there is immense lag. Im in my house at the time so i walk out, only to be greeted to what looks to be well over a thousand horses all staring back at me, all the same white horse. There's no way i can kill enough to make my lag go away so i guess that world is gone. Im not particularly looking for a solution but just thought it might be fun to share. Ive thought about maybe introducing another npc to kill the horses so if anyone knows of one im all ears.
