GUYS!!! CAW EDIT IN GAME IS FIXED!!!!!! THIS IS NOT A DRILL!!!!
I returned to the issue today, again, because I have this new world I have started. I was working on it despite CAW's edit in game not working. On the very same thread I posted my complaint on someone has now responded with a fix!!! AND IT WORKED!!!
**CRYING**
This ABSOLUTE GEM OF A HUMAN BEING has solved it!!
These are my steps if they help anyone:
My directory is : This PC > Local Disk > Program Data > Origin > Local Content (I had to search for my directory, the one I found under programx86 is where I found CAW, but it was not the current directory for the Sims 3. I noticed this was not the correct directory due to 'Into the Future' not showing up. I 'Search this PC'd for 'Into the Future', right clicked, and opened file location revealing my correct current directory.
I copy and pasted my CAW file into this directory
IT WORKED!!!
Please note that if you run on 12th Gen and need to use the PowerShell Script work around to launch the game, then you will also need to launch the PowerShell Script to run Edit in Game. No changes need to be made to the script!!!!!
