(Probably not germane, but for reference.)
I started playing this character again, after the patch.
One of my attacks (Scrapper/Street Justice/Crushing Uppercut) has enough "Knockup" that I can reliably bounce targets off the ceiling. With some frequency, targets will "stick" to the ceiling.
Most Nemesis bad guys stuck in the ceiling stand up, shift a bit, and fall back to the floor. The Tirailleurs will stand up and stay in the ceiling. I'm going to guess they don't do that "shift a bit" because they don't normally move, and that movement is the bit that triggers the "am I in the ceiling?" code.(Just guessing, though.)
