It's probably because of this line in
http://installer.pbwiki.com/LevelPlayingField-Monticello15 :

   SmalltalkImage current fixObsoleteReferences

Try running that and see if it helps.

LPF is running SmalltalkImage current cleanUpAll.

We recently started a convention that all classes that can free up some
memory prior to saving an image implement #freeSomeSpace, or #cleanUp.

One of the biggest offenders is Monticello, it caches quite a lot of
stuff when loading packages. There is a menu item for cleaning
Monticello caches manually.
