Brim incorrectly added printing teeth

Slicing "teeth_top" from here: https://www.thingiverse.com/thing:2736627/files using Cura 4.1

 

I'm trying to use brim to help them adhere to the plate and it fails to draw a brim for a few of the teeth. The same problem happens with support enabled/disabled, raft and skirt too.

It may be those teeth are not sitting on the build plate. As a test lower the teeth a mm or so and reslice.

Thanks! That seems quite possible - although shouldn't it build supports to them if they are not on the build plate?
