That's Life Competition No. 42

Puzzle 43
"Hi Puzzlers,
We’re very sorry to say that this puzzle is unsolvable. When we did our usual full checks before sending the section to print, everything was correct. But somehow, between us and the printers, an earlier version of the puzzle - that included the error- made its way into the mag. We are still trying to work out how this happened, so we can make sure it doesn’t happen again!
In the meantime, please accept our sincere apologies.
As a result of the error, we will accept any answer for this puzzle."
