Problem Description


I have been playing a modpack using the modrinth app but wanted more control over the server i was hosting so i decided to use AMP. Ive tried my best to follow the instructions on your website but im unable to play my original world as it keeps booting me into a corrupted world.

Reproduction Steps

  • created a new minecraft instance
  • changed the server setting to fabric 1.2.1
  • i then zip my modrinth folder and drag and drop in the instance file manager
  • i right click the and import configuration aswell as right click the server.jar from the modrinth folder and select set up as startup jar which it wont let me do
  • after im updating then starting the server
  • It lets me join the world but its a corrupted world overloaded with bugs

Start the server without the custom world first.
Make sure to leave the Jar as “Autoselect”, then set the server type to Fabric and set the proper Fabric version, then hit download/update.
If that starts fine, then import the world.
Don’t use any weird/sketchy startup Jars from modpacks, as they’re never actually needed

Thanks for the reply, ill give that a bash in a bit. Do you know any simple ways to import the world ? I would just be drag and dropping it from my mod pack folder into the file manager folder normally.

The web file manager can be a bit slow at times, so you’ll probably want to use SFTP to upload the world or any other larger files.
As long as the world is named “world” you should be good, otherwise you can change the world name under “Server Settings”.

Okay, I’ve managed to get it all working now, instead of dragging and dropping the modded folder as a zip which seemingly wasnt being recognised. I used the SFTP feature to drag all of the files within my modded folder to the instance file manager overwriting all of the default folders with the ones from my modded folder. Thanks for your help mate :slight_smile:
