As many of you have known, with the new 1.2 update after you convert the world it seems like things you have done have been rolled back. I now present your fix to this problem. I've tested this myself and it DOES work.
1) Navigate to your saves folder (Make sure to back it up first)
2) Delete the level.dat & level.dat_old files
3) Rename level.dat_mcr to level.dat
4) Navigate to the other folders in the saves folder and delete all files with the .mca extension
5) Reconvert and enjoy
Ah, good job. These instructions are almost identical to what I've posted twice before and each time it has helped someone, so I am sure you're on the right track.

Statistics show that people who tell others they need to get a new computer are twice as likely to use "gay" as a negative descriptor and will most likely never see genitals in real life, at least while not in prison.
