Autodesk Labs River Analysis Extension

I checked out the new River Analysis Extension made available May 9th on Autodesk Labs and I must say it looks pretty exciting.  I haven't actually run a design through it but I did install it and take a look at the user's guide.  It appears to be much more extensive than the HEC-RAS toolbox tool that we've seen in the past - this one has its own ribbon tab!
Hmmmm......Which of these pictures is just like the other? :)

Disappearing Survey Figures

Ran into something interesting and a bit scary today.  Within a certain drawing, if you ran the purge command with the "Purge zero length geometry and empty text objects" option turned on, it would obliterate all survey figures in the drawing.

I did some searching on this and although there wasn't a wealth of information, it appears that this isn't the first time this has happened.  Be advised, this was discovered in Civil 3D 2010 and I have no idea whether the problem exists in 2011 or 2012.
