When i open the scene the number i see in the cloud quality is "29.3333".
I rendered without changing anything.The small crop render time was 1.30 or so.
Then i tried a basic thing.I copied and pasted the same number "29.3333" ones more in the same input field.
Now suddenly the render time is 3 times longer.
Then i used "1" as input.The render time was roughly the same as when i rendered it as it is when i opened it.
Basically it shows "29.3333" but acts as it is "1" or so when you open and render the file.
I think there is no harm done (at least in my tests). But it looks frightening
Interesting.
