Sincerbox - one of the modders over in the Caw forum at modthesims actually explained that when a sim is in ghost form it carries just a shadow of it's files - then when it goes into controllable ghost it only carries half of it's files and half of the ghost play files; last when it is full resurrected it carries most of it's files and previous history, but because it has been dead at one point it will also carry memory files of being dead - so a ghost sims is a special character whose file is always different than any other sims - mummies are made the same way - so neither can be added to caw without creating a problem - as the game AI cannot put the files back in exactly as they are of a living sims that has never died - and because of this and the way the programming works it sort of confuses the AI (artificial Intelligence system) eventually breaking it down so it cannot handle the dead or previously dead sims at all. It is different if a sim is alive in the game and then dies and all it's files are in the game - the AI can look through it's life stages and put back what it needs in addition to memories of being dead - but if that sim is just added to the world in CAW - with the way porting in works most of the sims files are cleaned by the porting system so most of the info is missing and as any game when info is missing the files start corrupting.

You have to figure EA does not need to port in Sims - they are programmed in while making the base or ep, so all the files are always there. Even if we deleted every single sims - we are not able to delete their files that is in the programming completely - it is also why it is never a good idea to take an ea world and remake it by deleting sims - but that is another discussion.

Also you did not have to go through all that trouble of changing the graveyard as you can send a sim to a graveyard and place tombstone - then save the lot to the bin. They do not need to live on a graveyard to place graves. Also saving a lot to the bin saves all those sims files and that is why you can load non corrupting ghost through a save file or bin file. The porting system could never handle all those files.
