I have reports that were built with SSRS 2005, Ive been using them since 2005 and adding new ones as we go, we server around 100 different clients and server instances ranging from 2005 to 2014, but it seems that in 2014 when you use a document map and move down and then go back up it crashes the report, not sure if anyone else is running into this, but its a new one for me.
