as seen here, the bevel is now even, but it moves outward instead of in place with the rest of the groove inset,
*** Correction– so this image was just a normal bevel, and not the mean bevel weight modifier, when I tried now with mean bevel weight it still warped the same as in my first screenshot, the apply transform didn’t help at all. And again, all the verts are merged/ tested by this point. Curious.
