Huh, actually… I just created a new project using 4.5 and followed my own steps and was unable to reproduce the error! I also converted my old project from 4.4 to 4.5 and the original blueprint seems to be working, so whatever it was might have been fixed in-between version 4.4 and 4.5. I’ll look into it a bit more within the next few days before I’ll call it fixed but I’m remaining cautiously optimistic.
