Hello,
I have played on minehut servers for quite some time with my friends. We decided to use minehut because it was a good free server operator. Recently when 1.16.1 released minehut decided to patch both tnt duping and breaking bedrock with would ruin a lot of things in our world.
I decided that we should make a backup and start a new server untill they enable it again, but when I tried to download the world with /dl world world it didn't work because "failed to upload file". Then I tried with the Nether and it didn't work either. But when I did it with The End it worked.
So I started to wonder why this happend and then I saw that the files for Overworld and Nether are larger than 100 MB while The End is under 100 MB. So I checked the File.io website and saw that their max upload for the free version is 100 MB. I think this can be reason to our problem.
If you have the same problem please upvote so staff can see this and solve the problem.
