4095 Atom Smasher by Llig

This was a straightforward puzzle from Llig. The preamble warned us that corrected misprints in down clues would explain how to resolve clashes in 13 cells. The message was ‘The letters A to M are erased’ thus explaining the ATOM in the title. The grid was superbly designed with all letters of the alphabet used and all the letters N to Z remaining in the completed grid.

Corrected misprints are shown in [ ].
