I will check over it, but it did work the second time and finished rendering at around 3 hours. That was after pressing stop and restarting the render in the render queue from the image i uploaded to the topic.
Not sure why it did it, it was set to noise level 3% and a time limit of 05:30:00. Yet went on for 08:30:00
Maybe it just got a little confused, It's probably too hard to pin point the issue and in all honesty, probably not worth your time as i've used Corona for a long time and never had the issue before! Just thought it may have been something that cropped up in the latest build.
Unfortunately i wont be able to share this one, or not for a long time anyway.
Keep up the great work team!
