[MC-132097] Eternal "Loading World" when updating latest release world to pre-release after editing old world with MCedit2

Ok, so, I edited a world in MCedit 2 to reduce the file size and clear some distant chunks. I then opened the world in 1.12.2 (Latest Release), and it loaded just fine. When I go to upgrade that world to 1.13 pre-release (3 and/or 4), I get the "Loading World" text and screen, but it never actually loads.

I've tested this over 12 hours, just leaving it to attempt overnight. The only way to cancel the loading process is to kill the Java process through task manager.

Possibly duplicate of MC-132089.

MCEdit supports up to Minecraft 1.11

@Matthew, that may be so, but opening the world in 1.12.2 should convert it, which it does. But then I can't open it in 1.13 pre-3 or 4.

Unless this can be reproduced, using a current version of the game, without the usage of external editing tools, this report is not valid.
