Bloodsong-- Not to split hairs, but here's a direct quote from the SR3 pdf file: "Pro Pack Service Release 3 contains several fixes for known issues found in the original Pro Pack release and/or Pro Pack Service Releases 1 and 2." I believe I read the same line on CL's site. This quote explains why CL didn't elaborate on the issues SR3 fixes: they are known issues. Hence, we already know what they are.
