So, I was bored last night and tested some theories. I came up with a workaround for editing saves. Newer builds, at least 29 and up, save to a folder titled TheLustland. Opening the save file with a text editor shows things like "Cocklength_50_..." but there's a bunch of gibberish for the numerical value, as you well know if you've tried to do this in the newer builds. And using saveeditonline, you'll note that all of the body size/shape settings are missing.
Here's the trick. The older builds, (maybe 28, but I tested this with 24 and it worked) save to a different folder titled TheLustlandAdventure. They still have gibberish for the numbers, but when you open the save with saveeditonline, all the body settings are displayed. So you can edit all your body settings that you want in there until you get the desired effect. Make her really fat, really skinny, freakishly large boobs or dick. Once you've tweaked it to the desired effect, simply copy the save file from TheLustlandAdventure folder into TheLustland folder and voila! (be sure to save a copy in case you mess it up) Once you've done so, you can edit the newer settings that have become available like horse cock and new body paints and such. Just be careful not to adjust any of the settings that you set outside the limits, or you'll have to start over (hence saving a copy of your first tweak).
Here's a proof picture. You'll note she has a horse cock and body paint 4, so I didn't just fake the build number.
