(sometime in February, 2023) 4 off and 2 off is all I can get, atm. Hope to find 40, soon. Great puzzle and great find, hi19!
EDIT 2023, 24th June: today I started searching here again. Had troubles to find my 2 off again, but after that I got three different 2 offs, and then I saw something else. It was the 40. This is really GREAT short level. SO HARD to see!
