Modded Minecraft world crashing whenever I try to join it

[SupYB]

So the other day, I'm playing Minecraft with mods, one of which is the Morph Mod, and I kill an enderman that wasn't holding a block so it was classified as a new mob. But when I try to join my world later, the game freezes after it loads to 100%. I force quit and start the game again, and this happens 1 or 2 more times. But then after that, when I try to load it again, right after the world loads to 100%, the game crashes and I'm greeted with this:

---- Minecraft Crash Report ----

At first I thought it had something to do with the Morph Mod, but now I'm having second thoughts. I've searched for hours on how to fix this but none of the results were about this specific issue. I'd load a backup but the last backup of my world was 5 days ago (March 15th) so if I load that backup, there'll be quite a lot of stuff that I'd have to redo (i.e. making the amazing giant fountain in my village, getting decorations and weapons from Minecraft Dungeons villages, finding and adopting some random MCA orphan living in that Dungeons village, spending quite a long time trying to make a traveler's backpack, summoning and killing the Grim Reaper to bring back dead MCA villagers, crafting a mini bus + golf cart, and WRITING MY JOURNAL ENTRIES FROM THE PAST 5 DAYS!). There's so much I've done in the past 5 days and I'd hate to see it all gone. I don't know specifically what mod is giving me these issues but the report mentioned Abnormals Core. Please help!

 

 

 

Edit: Actually I haven't played Minecraft for a few days because of this, so my most recent backup could maybe, just maybe, have my latest data. I'm gonna go check it out right now, but I'm still requesting assistance.

Realization of something

There is an entity in the world with the same UUID as the player joining. My guess is that this entity was left behind by Morph. You'll have to remove this entity, probably by opening the world with a different UUID and then killing it.

You mean like deleting the Enderman.json file in the mob folder in the morph mod config folder? I've removed it from there before but I never really loaded the game with it like that...

 

Also how exactly would I open the world with a different UUID?

Need for further clarification

I meant using the kill command to delete this entity once you have logged in.

Still confused...

i don't know if this would work, but you can use a NBTExplorer to read the level.dat file and change the difficulty to 0 (in Data). Then join the world if this works all hostile Entities will be delete
the other option that comes to mind would be to move your world to a server, launch the server and kill all Endermans from the console
