...and fixing the mistakes I made trying to do so. I tried out the new 1.14 update, and made a backup beforehand. I decided to go back to 1.13, but my attempts to restore the backup failed and I may have cause some problems copying files, i.e. there might be several copies of my world. I just want to restore a backup and use only 1.13. If I have posted this in the wrong place, please direct me to the correct area. Please help a Minecraft newcomer.
