Has Articulate 360 any features for feedback in the publishing sequence?

It doesn't give any feedback whats wrong when I try to publish. It ends somewhere in compressing images every second or third time, vhen I try to publish. What kind of images is uncertain, as long as it don't give any kind of usable feedback.

All I know is that it's the last slide I added. When I remove it, all works fine.

Is there any good way to troubleshoot when publishing?
