Well, this is ... odd.
I bought Posemaster during the PA sale, installed, everything’s fine with that. I defined some custom actions, as explained in the manual—and I’ve done that before, so it wasn’t a huge deal. Added them to the Custom Actions section. Added the icons, stuck them in the basic viewport tools section of the “Actors, Wardrobe and Props” toolbars, and everything was fine. Applied and Accepted the changes. Started and restarted and the icons were there and functioned, no problem for a few days.
Started up the program today, and the icons are gone. The Custom Actions are gone; they don’t show up in the Customize section at all. It’s like I never did anything.
How on earth does that even happen?
I redefined the actions, and it’s clear that I did it before—everything is pointing to the same folders—but somehow everything just disappeared.
