Thanks for your reply.
Before everything went wrong I was working on Super Brainz and Acorn to get them to master rank. They were both on Elite or Super Elite rank so I was close to getting both to Master rank. They were to be the 19th and 20th promotions to Master rank for the final trophy in the game (promote 20 characters to Master rank).
After the restore they were put to Master rank (where they weren't previously) therefore I could no longer promote them for this final trophy as they are already there.
Therefore I have now unlocked Wizard and Wild Flower characters to try and get them both to Master rank. I'm just hoping with all the wiping and restoring of data, the game remembers I've already promoted 18 characters and these two extra characters count as 19 and 20 for the last trophy.
Please don't make any further adjustments or restores to my account now as I've made progress in levelling up these final two characters. Another week or so I should have both at Master rank and I'll keep my fingers crossed this last trophy unlocks.
