I have a 341 Mb world that im trying to make a realm so that me and a few friends can play. The problem is that everytine I try to make the world into a realm once it finishes it immediately switches to an error has occurred and I've spent hours trying to figure out what else I could do or a fix but haven't found anything. This is getting really annoying as each attempt of uploading it takes about 30 minutes.
