Ummm.. history says I'm probably doing something wrong, but I can't even get the drawing to stay open. It opens up, I click, I automatically get the request to open the block editor and poof it's gone. A recover opens a drawing with an exploded block... something funky's goin' on. Will play with it some more.
Edit: Ah-ha!
1. Civil 3D has taken an ealry weekend
2. Leave the parameter and action where they are and move the actual symbol for the flip onto the back of the drinking fountain. then you can't tell if it's being left behind or not because it stays somewhere on the line no matter which way you flip.
Doesn't fix the "why ain't it.." but no one else has to know it isn't working
