When I moved addresses and went to do my tm30 for some reason they gave me a new 90 day report also (I think they didn't see the old one inside my passport and gave me a row but not a fine when they handed my passport back with the new one). I was just going to go tomorrow (my original date) incase I need to, but now I'm really busy and it would really be preferable not to. Is it safe to assume the new one overrides the old one and I can just go on that date. Yes, I should have asked at the time but I was confused about what they were telling me at the time, took me until I left and looked inside the passport to fully realise what they had done.
