I have a full grid apart from 29A which I can't work out at all, even given the three possibilities for most of the letters. A hint would be welcome. Like others I've failed to see the ambiguous entry - which of the 4-letters downs is it, s-p?
Hi Cockie - 29a was one of my last ones too - ridiculous! It's a simple 'hidden' (indicated by 'shows'). The down one that fooled me was the one with spot as the definition - could end in B or T.
I think you have something very wrong - there is no clash at all between 6a and 9d - both are 'L'. The other one is B/D - all clashes are consistent in a way - that doesn't mean they are all the same clashes though if that is what you are getting at. Hope this helps.
