I have a world save from a friends' private server (not minehut) that over 500mb and I'm trying to upload it. If I just drop the .zip into the world settings, it hibernates before its even 10% done. If I stay on, nothing happens when it's done. If I get on then get off right before it's done, nothing happens. Can anyone help? I tried the official tutorial method, but the file.io site cant handle larger than 100mb
