Level streaming don't free memory

Sorry for my english. Can somebody help me to understant what I do wrong with level streaming. I have a problem, when I unload ~3k objects, my memory stats de facto don’t changing

My initial guess is that the garbage collector hasn’t run. Have you tried calling manually calling Collect Garbage?

I know for a fact that texture streaming doesn’t behave the same in editor as in production. It’s probably the same for level streaming…
