So i just started a minehut private server for me and my friends and i tried to upload a world (it wasnt an unedited world i already built some thing in it) and when it finishes uploading it shows a blank box in the bottom middle of the screen with an x in it and when i entered my server it wasnt the world i uploaded but instead the default world. even after restarting the server and reuploading the world nothing changed. Does anyone know how to fix this?
