I'm well chuffed, having finished this one virtually unaided (I would never have found the misprinted S in 31ac without help). Just the right standard for this feeble brain.
It's a pity the preamble doesn't ask the solver to highlight the resolved clashes as well as the boundary (maybe in a different colour) - that would have been pretty.
I can't parse the answer for 30d (a synonym for 'throw?) - any help gratefully received.
