Experimental copy

Hello Mojang/Microsoft

I had a big problem that when I am trying to change my 100+Gb map to experimental gameplay and it wants of course to do an copy of my map.

But when I’ll try to do a normal copy or change it to experimental gameplay when it came up to 40% it stops and says failed!

Please fix it Mojang/Microsoft.

BTW the version is 1.13 and not 1.12.1 but it wasn’t added there so I had it on 1.12.1

 

Best Regards
