hook up a 3A timer in the rooms for them to be recognized still.
OR
go buy a Cord Coupler adapter to continue the daisy chain in each room you sold a bed for.

by using the adapter....some room numbers in that chain of beds you sold will be changed and moved around. Room 6 will now become room 2...and so on and so forth.
If you dont' want that....you need to put a 3A timer in there.
