GSJ, I finally got my Hoth playset today (actually a week ago, but it took me a while to pick it up from my mail place) and when I looked at the pic again, the 2-1B had indeed come loose from the twisty tie, but I panicked for a sec when I picked it up because the window was slashed right in the middle. However, I stopped freaking and shook the set upside down, and there was the little droid pal, hiding behind some display packaging, so it's all good.

So, thanks again GSJ!!!
