It's ironic.
The sorceress lair quest script used to call the familiar trainer, which had a specific list of items, effects, and skills that it would invoke to try to get the familiar up to 20 lb. People complained for years that it didn't do this or it didn't do that.
When the maximizer was created, the complaints turned into suggestions/requests/demands that the quest script use the maximizer.
It now does so.
And, having caved into the repeated demands, it is now apparently a "bug" that we do what the maximizer says, rather than use the familiar trainer and its fixed list of items, effects, and so on. Makes ME not want to put in features unless they specifically improve MY KoL/KoLmafia experience and behave exactly the way that I want and expect them to behave.
