New update compresses the save data, I managed to get this to work by unpacking the save data which is now compressed as .lsv with the LS Tools.
After that repeat the process shown above with the save game swap, except you have to upack both saves, delete the .lsv of the save you wish to edit and then copy over the meta.lsb and the sanity .lsb from the save you are copying the mod data from.
That got it to work for me now of the .72 update
