Images not autosaving


Recently i encountered a problem that a few images would not autosave during a sequence.
About 6 images in the sequence it stopped autosaving. later on i restarted and the problem was over.
But i like to know what happened, and how i can prevent it.

Here’s the log:

We cannot properly troubleshoot with partial logs. Please see below and we’ll take a look.

Also, did you use the “navigation arrows (green back and forward arrows)” to go through your images prior to this crash?
