Clipping tool bugging out

I'm trying to clip a cylinder to make a 1/8th slice. I clipped out the 1/4 piece just fine, but when I come to slice at the 45 degree angle through the centre, I can only clip on one side - I can't let the other side survive. Pressing shift-x cycles through either this:

or this:

Then I tried to outsmart it: I duplicated the cylinder then used vertex edit to smush all the righthand vertices together like so:

but I am foiled again:

This doesn't seem to be a problem with the VMF saving the vertices wrong: it happens on old solids and new ones I just made.

I have no idea why Hammer is okay with the righthand pizza slice but not the lefthand one.

pls help

If you try to clip on an existing offgrid vertex, it can make a microface where the clip intersects the vertex.

Manually make the brush?

Try snapping all your vertices to the smallest grid size by selecting all vertices of that brush and pressing CTRL+B
This will fix that issue:

You might have that, so yeah doesn't hurt trying.
