Hi,
There is a strange behavior occurs with the latest builds. Sometimes corona calculate only 4 or 5 passes then stops suddenly. I didn't set any limits to passes count or time I just working with noise limit (usually 3.0) and of course it doesn't reach that limit after 5 passes. The same issue occurs with IR it calculates 4 or 5 passe then recalculate again. I think it is a bug or something else because it works well after restarting the max but unfortunately it occurs again after short time. Today I lost 3 renders because of that issue they was saved after 5 passes only and I didn't notice it because I left the office after running batch render.
I hope you can solve it soon because I worked with that build version in a commercial project and I want to complete it correctly.
Thanks
