Corona 12 update 1 - elapsed render time

[CharlyRT]

Hi, has anyone noticed something strange while rendering with Corona 12 update 1?
Yesterday I was rendering a 4k image at 4% noise level limit, and the render time was changing from 4hrs to 330 hrs, to 4hrs again and never decreaced remaining time
Noise Level was progressing fine, I stopped at 5.5% in 2 hrs, but the message of remaining time was acting a little strange.
Im not an expert in Corona behaivior, as a Progressive render engine I havent seen something like this, could it be related to something odd in the scene?

The only time I recall seeing something at all similar was when I was restarting a render from a saved CXR - any chance you were doing the same thing? It only happened to be once so never dug into it....

Hi Tom
No, its rendering from scratch, im doing another test in another computer, hopely I could take a picture, unfortunately I cannot provide the scene

TY for the extra info! I haven't seen it happen myself out of that one scenario, let's see if anyone else has anything similar happen, and let's see what happens on your other machine too. One thought on the scene, you could delete EVERYTHING and just send it over as an empty scene, so at least that way we can check through scene settings in case it's something in there causing the issue. If you delete everything 50% at a time, you might also track down whether there is an offending object in the scene too ;) But that does take time to do that repeat testing.

Thanks Tom
Its still happening in the other PC, I upload a pair of screenshots
Ill try to upload an empty file from the scene.
