Progress Loss (SBC Base Icon Upgrade)

I was completing the Base Icon upgrade last night. I completed the 88 squad but ran out of fodder for the rest so was waiting for my Sunday rewards. I have gone on tonight and it has reset and I’ve lost all the players and coins I put in to the sbc. It didn’t say a time limit I had to complete it in but still lost all progress. I’ve spent a lot of money on FC points and think it’s a joke that they have taken away my coins and players without any explanation. I would like FC/EA to reimburse my players and my coins as it wasn’t clear that it would reset.
