Quarry has images for clay pit

Noticed on my present game that some of the quarry images are clay pit images rather than quarry images.

Quarry (5,4) => (6, 7) are the problematic images.

Thank you for that - I see that this was fixed in the Standard version some years ago: I must have missed this. I have now copied over the fixed graphic, so this should work correctly now.

Thanks James!  Confirmed fix in latest nightly build.
