Tomodachi Life is problematic.
When Nintendo patched the Japanese version of Tomodachi life, removing a glitch that allowed players to participate in same sex marriages, what they did was actively remove the ability to create an apparently unintended type of relationship. Then, in the patch notes, roughly translated. The patch ‘fixed’ the ability to create relationships that are “altered”. Nintendo maintains this change was made to prevent an issue where the game could not be saved.
