Sorry this was published a little late rather than midnight. Another topic - noticed another hacker dumping their sql injections into the chat. I will try and devise a script to alert me. Drop me a note if you see it happening again. Always appreciated.

 Thanks for the pleasant beginning of Easter week.
Just like Klaus stated: the UR is the egg to be found

 I needed UR in both A2 and E6. Are there more UR's?

 @MrL: yes, the one that solves is more tricky, but perhaps it is too early for a spoiler.

 @hoke: these two UR's solve the puzzle, but it is interesting to know that tricky one!

 @MrL: Ok, the UR in E6 has 2 variants, the simple one removes 5 and does not solve.

 Mmmm, just settis here, no UR. A lucky mistake maybe?

 We also used two URs on E6. Besides that standard tools. Nice exercise.

I used a Setti on 9 in the end that solved it for me. So I am with John that it is just settis.

 Thanks for a very nice puzzle. Not difficult, however, VCE needed some time.

 May be I'm wrong, but I think that the solution is not unique. I've found two solutions that appear to be valid. As to the validity of the solutions, the solver seems to be of the same opinion.

 Correction to the foregoing. The solution is unique. But the solver doesn't recognize all invalid solutions.
