Assets with "mirrored" checkbox will desync direction between UEFN and live edit

Summary

This doesnt happen to all props, but it 100% happens on specific ones. I dont have the exact asset that it happens, but if you place down multiple Village roof pieces, you ll eventually find a piece that it happens (it happens on a lot of doors too, but for now we can repro on roof pieces). This generally causes architecture to flip during gameplay and mess up structures and the level.
