You mean it will not work with the new patch, or corrupt ANY save I'll try to modify?
So, you mean the editor need to be updated too?
It works as fare as I can see, the only time you may get an Inf. load time is when you try to Mod someone other than the main 4 Char.
This part should be known without being said but I say it any way. If you add an item and spell it wrong or ad one that's not in the game or picked up by the editor it will corrupt the save and you may get an Inf. load time as well.
