[Cura creates random membranes]

I see no red in X-ray view. Please note that I included the file in the first post.

Why would only one or two of them at random exhibit this behavior?

[Cura creates random membranes]

As I try to print five hexagonal towers, Acura seems to insert randomly a thin horizontal wall on some. They seem to be different on every slice, sometimes there are one sometimes two. This was on Cura 3.2.x but I was also able to reproduce on Cura 3.3.1, both times on a Mac.

 

the resulting print does include that thin wall, on two out of five towers. I thought it had to do with adaptive layers at first but it remained after disabling any beta feature.
