You can view, choose or change your seat during check-in: from 30 hours before departure (24 hours for flights to and from the United States)."
I'm still able to see the seat map for my incoming flight to AMS, however. Is KLM possibly planning an aircraft swap or schedule change, hence the missing seat map?
No; they (and many other airlines) disable the seat map once a certain percentage of seats in your cabin are selected.
