What I am thinking of are those changes made to deal with one issue that just create a different problem. 2 examples I can think of are :-
FGW HST refurbishment. Complaints about the chronic overcrowding so to enable more seats to be fitted most of the tables and the mid carriage bulkheads were removed leading to complaints about the lack of tables.
14X/150 3+2 seating very unpopular so replaced with 2+2 reducing the capacity and leading to overcrowding.
