Update V2.62 resolves all issues with completing Fifth Anniversary level "Glory and Celebration" in S&L, and in fact, I've posted a solution video for the level, though I recommend that you try the level first, as this is one terrific level - challenging but fair, with internal hints and some fun graphics.
I haven't been able to find posted solutions to any of the FIfth Anniversary levels, which it's why it's taken a while to verify them in S&L - they are all interesting and tricky levels, and developing solutions on my own takes time that I won't have until the issue list is whittled down a bit more. Does anyone know of posted solutions to these levels?
