Minecraft 1.12.2 Forge Help

[Logan4629]

I'm very new to forge and Minecraft mods in general, so my problem might be something simple that I just don't know how to fix.

 

I'm using the recommended version of Forge 1.12.2, I've tried the latest, and I've tried all the way to 1.7. The game launches completely fine, and all of my installed mods work great together as well. I've uninstalled all of my mods and created a completely new Forge profile with no mods other than the 4 that installs with Forge. 

 

My problem is that my saves are being deleted after saving and exiting the game. I believe it has something to do with this "Couldn't get hash" Issue. I've searched for others with problems like mine, but every other forum I've found has a problem with the game crashing alongside this error, which isn't my case. 

 

Below is my "game out-put" that includes the 29 warnings I get every time I launch the game with, or without mods.

I'm truly sorry if I've formatted, or added my logs incorrectly. I used PasteBin but I'm not completely sure if I used it correctly. I hope I have supplied enough information for support.

Thank you.

Sorry that this is happening I don't think that the couldn't get hash for the issue would cause this but I could be wrong. I think it is more likely a permissions issue.

Could you post some more details:

• Could you post a log where you actually enter the game and load up a world?
• Could you check the permissions on your Minecraft folder?
• Does this also happen in vanilla Minecraft?
• When you say the saves are deleted could you check when you create a world if they appear in your saves folder and when if at all they disappear from the saves folder?

If I did everything correctly, the permissions on my Minecraft folder are fine. It says full access to every permission listed under properties. 

These errors do not occur in vanilla Minecraft.

The saves do appear in my saves folder, when the saves vanish from the game however, they do not vanish from the saves folder. They still appear there but not in game.

 

I apologize for the late reply, I was asleep at the time. Is there any solution to the hash issue? Even if it isn't causing my saves to flee.

 

Thank you

So I'm assuming the missing world appear when you run the game in vanilla.

• Could you try to open a save file in vanilla that was created with forge mods that you don't mind possibly losing (or just make a test one in forge) and tell me what happens? I just want to rule out the possibility of the saves actually being corrupt.
• Are the regular files in the saves folder or are they empty?
• Also, do you have any mods that are modifying the main screen, terrain generation, coremods installed that may cause issues?
