I created a Sim that was "living off the land" and off the grid while foraging, collecting, and fishing, with a very small footprint, but was not living in Evergreen Harbor world so that they could collect all the plants growing in one neighborhood over a period of three days before moving to a new lot in a new neighborhood. The Sim was working in the Civil Designer career to make a little extra income from home to allow the Sim as much time as possible to forage and fish.
The first three Civil Designer career levels were easy peasy to deal with. But once the Sim hit the fourth level, they selected Civic Planner and issues started showing up, making it more difficult to perform the daily career tasks. For example, one of the tasks is Interview about Neighborhood Action Plans (Interview another Sim about Neighborhood Action Plans at a Community Space Venue.) Long story very short, I needed to put a Community Board on my Sim's current lot, invite someone to hangout at the lot, and then I could interview them. It was the ONLY way to interview another Sim.
I searched the internet with the following question. "I can't seem to interview another Sim about Neighborhood Action Plans or Utilities."
I also learned that the option to Interview another Sim won't always pop up easily unless the Sim is on your lot along with the Community Board also situated on your lot. If the interview options won't show up when you start to chat with another Sim, select the "Other Choices," "Friendly," then select "Interests." This section is the chat area that will allow your Sim to Interview. However, again, as pointed out, you may need to invite that Sim to your neighborhood lot, making certain that the Community Board is also on your lot.
In other words, IF you "scroll" through the chat options under the "Interests" section, and there are no "Interview...." choices to choose from, you will need to ensure that there is a Community Board in the neighborhood, as described above.
Another issue has been to Rally Votes. If you don't have a bunch of Sims on the lot with the Community Board at the time you initiate the Rally, you have wasted your Sim's time and energy. Your Sim can't rally again for several hours.
If I encounter any other issues, I'll add them to this page as my Sim continues to work their way to the top of the career outside of Evergreen Harbor.
