Recently upgraded to 1.2.0 to test something out and when reverting back to 1.0.16, my subscene wasn't showing. After checking the subscene gameobject, it showed that the script doesn't exist.
When I create a brand new subscene it seems to work but the script still doesn't exist, and reloading unity just breaks it again.
When I create an empty gameobject the subscene component doesn't show up on search.
I tried reinstalling the packages but it still doens't work. How do I go about fixing this? Last resort I can just make a new project and move everything over, but I'm pretty far into development and would take ages...
