I have completed this type of offset many times and never had this issue. I tried grouping the shapes, making sure each shape was a separate shape and everything else I can think to correct. I get the same two shapes with the outer point clipped off. It doesn’t matter if it is 100mm or 1mm. I have deleted all and started again and the same thing happens. Bevel also does something different to the same two corners. All the others are flat but those two for bevel are more rounded.
If you can upload your LightBurn file that would be a great help.

I did it like 10 times in different ways and it always clipped some corners. Not always the same ones. Here are two simple ones in which it clipped the corners of one but not the other. The clipped one is not the same as the other because I created them differently. Not the same as last night because I didnt save them. I have been making geometric shapes for a while (months) and not had this before.
If you zoom in on the offending ‘petals’ you will see that they don’t go to a point, they are a straight line. Offsetting is making this more noticeable.
If you edit the nodes the problem will disappear
That is exactly what the issue is…I would have sworn I zoomed to that extent to see the nodes as that is a simple thing to check. It seems that the program corrects those flat spots most of the time when making the “petals” from the original array of circles. If I zoom in none of my circles align exactly in the center and the outer circle doesn’t land exactly on the junction of the array circle. That not exact junction of the 3 circles in one place is whats causing the flat spot or line at the tip. However most of the time Lightburn corrects this itself. These 3 examples Lightburn corrected it 2 out of 3 times. Go Lightburn for fixing my sloppy shapes 99.9% of the time. You made me think I was better than I was until the times you didn’t fix my slop.

I’ve been down this node road more times than I care to remember ! glad I could be of some help. Thanks for showing your process for creating the final design
The issue is back and this time the corners are not two nodes so close. I was pretty sure the original issue was not that simple. Outward offset makes flat spots. The inside points are actually flat spots and not a point but I dont care about them as they get deleted in the end anyway. I am using the corner and not the bevel or round.
