I created a blank project with a button that reloads the same scene. After quite a few clicks on the reload button the RAM usage steadily increases, and this is a fairly blank scene!
I am using Unity 2019.1.7f also have tried it on 2019.1.1f

This is killing my main project right now and I’m not sure how to free up the usage without restarting unity.
