respectfully that is too unfriendly. I think they nailed it -- leave existing alone, and prevent new ones out of season, with them coming back available each year. Breaking stuff, esp stuff that was just for fun/silliness, just feels harsh and against the whole spirit of the 'this was for fun' toys. And thinking from a released game perspective, and casual players ... they are not gonna dev command, they are just going to complain if you do that to them -- in large numbers, most likely.

Exactly the reasons they should not be removed from build menu.
