I have had the same thing happen with the last three tax returns I e-filed.  I went back into to print out the 9325 for my file and got that message.  When I hit the button to show me what change it pulled up an amended return taking out the entire RR credit that I took on the return which was appropriate on all three returns.  It didn't change the return itself.  I am so relieved to hear it is a bug.  The first time it happened it was for a very difficult, high maintenance client who was supposed to get the full $1,800 on the return and I dreaded telling her that she might not get the credit.

I guess all these bugs will be worked out by April 15th??
