My world is 234.4 MB and crashes whenever I try to convert it. It always converts to 4% then crashes immediately after. I have tried duplicating the world and converting the duplicate, uninstalling and reinstalling both versions of minecraft, and tried converting in the 1.2.3.3 beta but nothing works. I sent in my world and my receipt number is 280e3314-4db2-83f-c-cbb7-782b96209c07
