I'm playing a modded version of Minecraft 1.14 and I've been playing for about an hour and a half of my newly made world and I just now ran into this problem where all the mobs in the world hostile and passive have frozen in place. Other issues like commands don't work, when I exit to title screen the game freezes on "saving game" and I have to force close MC, and when i do exit out of the game, it puts me back a few minutes in playtime when I get into the world again. Things I've checked/done: Restarted Minecraft, restarted PC, I tried checking the tick speed but commands don't go through (i have them enabled). Anyway Ill list mods here just in case (I play on fabric api rather than forge): voxelmap, adorn, aestheticism, animalnet, anvilfix, appleskin, appleZ, aquarius, battletowers, betterthenmending, blockus, couplings, durabilityviewer, dynamicfps, extrabows, extradiscs, fabricblocks, fencejumper, fishtraps, glassdoor, glassential, grindstonebooks, harvest, HWYLA, iamverysmart, inventoryprofiles, justsleep, leadvillagers, level up hp, mambience, mobZ, moEnchantments, netherthings, optifabric +optifine, oysters, phosphor, presence footsteps, roughly enough items, shulkerbox tooltip, simple teleporter, slightly altered terrain generator, soul shards, torohealth, tweakeroo, vanilla hammers, and Wildworld.
If you need any more info lemme know (and how to post them, Im new to this)
