In version 2.0 of Source Media Arcade any customizations that you make to the map or to your item library during play will normally be saved when you close the game or change maps. In most cases this is fine, but some people have unstable computers and would feel much better if their changes were saved instantly to avoid possibly losing their work due to a crash. Today I added in a new Boolean console command called “persistent_save” that will instantly save any item file or map arrangement as soon as you make changes.
