KiCad Compatibility across Platforms/Possible (likely)Bug

Still trying to work out what went wrong:

Edge Cuts Curiosities

There are two questions that come to mind regarding Edge Cuts. 1: Continuing the discussion from Margin or Edge.Cuts: Note: @dchisholm quote was posted because it was the easiest/first one I could find. OSHPark Board Outline We recommend a small but nonzero line width; the fab will route so the edge of your board is at the center of your line, no matter how wide it is. What is interesting is that I uploaded to OSHPark a Gerber with a 2"x2" board with 0.5" Edge Cuts line width. The autom…

As far as I know, these files are from a machine that does NOT perform frequent updates to KiCad. When asked, the user replies as using the 5.0.2 Version of KiCad, and that remains the reply even today.

The same file was archived(zipped) and sent to me. There were some minor changes to the design, but for the majority of the design remained the same.

Here is line #1 of the two PcbNew files:
(kicad_pcb (version 20171130) (host pcbnew “(5.1.0)-1”)
(kicad_pcb (version 20171130) (host pcbnew 5.0.2-bee76a0~70~ubuntu18.04.1)

For troubleshooting reasons I need to address the Second version first. This is some of the text in the Pcb file:
(gr_line (start 101.6 101.6) (end 152.4 101.6) (layer Edge.Cuts) (width 0.15) (tstamp 5627043C8A50))
(gr_line (start 152.4 101.6) (end 152.4 152.4) (layer Edge.Cuts) (width 0.15) (tstamp 5627043C8ED0))
(gr_line (start 101.6 152.4) (end 152.4 152.4) (layer Edge.Cuts) (width 0.15) (tstamp 5C2B12D3))
(gr_line (start 101.6 101.6) (end 101.6 152.4) (layer Edge.Cuts) (width 0.15) (tstamp 5627043C97F0))

Then the really weird entries in the First version:

(effects (font (size 1.5 1.5) (thickness 0.3)))

All of these lines should have been on a different layer.

This is a college graded project and I can not post the entire project online.

I am confused that one of these has timestamps for graphical elements. This does not really make any sense.
Especially the fact that the timestamps are clearly in 64 bit format could point to a bug.

[paulvdh]

For most of the timestamps I count 12 (hex?) digits, which suggests 48 bits, not 64.
