Finding this tricky - I have nearly all the answers but a grid that barely fits together and doesn't quite work, even with clashes galore. It's hard to know what to ask, but:
1) It looks like the 11-letter down entry should start in the top row and end in the bottom row. Is this correct? If so can anyone hint at how the heck that works?
2) Earlier in the thread, someone suggests 2D should occupy 7 spaces. Can anyone hint at how that can be?
Thanks.
