I simply restored the old enable sliders script I had from file restore plus a bulge slider that was there too, since my huge exception file mentioned bulge slider about 50 times and then installed the new height sliders alongside them. You will need the script AND all the sliders (hands, neck, bulge, etc). Yes that was what I explained before, and yes, I should have mentioned that you still need the scripts from the initial post on this thread.
If the scale was increased to make the differences more obvious then you would end up with disproportioned Sims. Changing the bone that gets scaled, to fix the toddler issue, has meant that the legs and feet do not get scaled making the size change less obvious. I've also come to the conclusion that while the scaling may be the same values in the code, the difference is not as noticable as before since now the Sims are only scaled from the waist up.
That hasn't been changed and hasn't been included with the new files. People trying these new fixed file will still need the original script file from the original downloads.
