Ok this is good to know and I'm hoping it's exactly what you've said and will perhaps Coke and go depending on the temperature etc. I guess the best thing is just keep an eye and see what happens?
It may be wise if you are going to suck it and see to get the tiles that may be required for a repair now as they may not be available in the future . But if I was you as mentioned earlier leave it for now as if it ain't broke don't
