Okay, so given that, v26 is missing a move called Drop Science (referenced on pages 6 and 39.)
This is the wording from v32:
DROP SCIENCE: When you consult your knowledge of a specific topic or determine facts about your environment, roll +Craft.
-- On 10+, the GM will tell you give you a useful, specific detail about the situation, or ask you to make something up.
-- On a 7-9, the GM chooses one:
---- They’ll tell you something interesting, but it’s on you to make it useful.
---- They’ll ask you to make up something interesting, but then they’ll tell you what else you’ve heard that complicates things.
And from the Digest Edition, v1.3:
DROP SCIENCE: When you consult your knowledge of a specific topic or determine facts about your environment, roll +Skilled.
-- On 10+, the GM will tell you give you a useful, specific detail about the situation.
-- On 7-9, the GM will give you a general impression.
The v32 version seems to be more in line with the other moves from the system, but that's just my opinion. Given the fact that the move is referenced exactly thrice, it might be dropable. The 'determine facts about your environment' part is already covered under Check the Situation on page 4 anyway. We could easily just add one more question to the list. "What do I know or have I heard about X that seems dependable?"
