Missing infill?

Wondering if anyone can give some input on this one. I noticed the second layer of a print just skipped a part of the infill. Attached are some photos (one has the area circled in green since it is hard to notice):

If I check the same layer from the sliced file it looks fine:

Any idea why this would happen? I am on firmware 6.0.0 but haven't been able to find anything related to this issue, yet.

RE: Missing infill?

Looks like a there was a small issue in the filament. Somehow no filament came out of the nozzle for a short time. 
Looking at the pattern before and after (and the preview) I assume the machine just did the gcode as it should. 
- Small irregularity in the filament? Causing less grip from gears on the filament 
- Not dry enough? 

We will do what we have always done. We will find hope in the impossible.

I observed this again today. I didn't get a video but I was watching the first layer. When it happened it started at the "r" in "Cilantro" and stopped extruding and started slowly moving directly towards the purge block. It wasn't doing any travel moves to extrude the "r". Almost like it just skipped a whole bunch of stuff.

RE: Missing infill?

you made an image of preview. There you see the same movement? 
If so, probably an error in the g-code.
If not, issue in the printer. And then you need help from prusa. Maybe a bug in the firmware? 

We will do what we have always done. We will find hope in the impossible.
