The only difference is in the weight of the Platypus.  We're expecting 2.29something but now getting 2.3.  As the Platypus is actually added with a weight of 2.3, I think the change is due to improved string/float rounding in this version of Python (noted as one of the 3.1 changes backported to 2.7 here: http://docs.python.org/dev/whatsnew/2.7.html#python-3-1-features).  I think we can fix this by simply changing the weight here to be one that won't exhibit this anomalous behavior between different Python versions?"		closed	Uncategorized	1.1		fixed			Accepted	0	0	0	0	0	0
