I have a Moscow World I have been working on for 4 years now, I have made copies in the past so it might not show that it was made 4 years ago. But unfortunately that my World had some bugging issues due to blocks not placing. It would place the blocks and delete itself from where i placed them. Once it started doing that, I start to make Copies just incase of Corruptions. So after i made the copies, I went on one of my Copies and it would Crash under a minute. I've tried many Methods but nothing seems to fix the Issue. Hopefully its not a violation I did because people have came on my World and Placed Symbols I'd prefer not to be on my World. If this bug could be fixed this would make my day. If you can let me know any fixes in the future let me know.
