In the advanced output, mirror X & Y are yielding strange results:

I would think that mirror X & Y should flip the slice on its center without changing the position of the slice itself.

Mirror X and Y mirror the position of the slice *across* the X and Y axes. They are mostly there to help with stage input mappings, that are often symmetrical.

Thanks Joris but the term Mirror X or Y is misleading since what this function does is just a move not a mirror. I would think that Across Screen X or Y would be a better description

In my opinion, to be helpful with symmetrical stages and building complex symmetrical maps the slice should also be mirrored (flipped) as well on its corresponding axis.

Yeah, it's going to mirror its vertices as well in a future update. It might even make an automatic duplicate.
