thanks @ VaughanM for discovering you must save before unreal will recognize changes made to VSC
After making changes in VSC you must:
-
Run Build Task
-
Save
-
Compile in Unreal with Live Code
After you are done working in Unreal and have saved and quit, you must run Build Task again in VSC in order for changes made in Unreal to save the next time you open it. (as mentioned in this video.)
