Right now, these serve no actual purpose and just give out an illusion that they define something, when in reality not much. Welcome lot can be pretty much any other lot with other category, since it doesn't function any way different from others and any lot can serve as its define theme because people everywhere else are pretty much helpful. My first experience when I joined the game first time, everyone everywhere literally acted like my mom in a sense that they guided me and taught me the 'first baby steps' into navigating this game and what not. For example when I said any lot, a service lot that has the same motive decay difficulty (easy) and newcomers can just consult other veteran players with questions, serve newcomers and comfort them to feel as If they at home. Point is, welcome category/type isn't needed since other ones can carry its task (like especiallyy service lot, and it's not like the community can be toxic at times, which I have yet to heard from anyone). Don't think there is much to say about off-beat (off-beat doesn't give special objects or much benefits, so you can always set those to function as games, entertainment or romance). When these changes are applied, the pre-existing lots that have this omitted categories will set back to the default "None".
