I'm sorry for the long, and not planned for, break. The legacy wasn't updated in a long while, and every now and then someone asked about it. Knowing that some readers missed it meant a lot!
The reason I needed a break, is that I got the build+save=crash problem, and that the community system that worked fine when all houses was played on a routine (SimBasic), doesn't work as well when I mostly focus on just one household.
The crash problem was solved, and I've come up with a more generic community system - money wise, no longer depending on their bank accounts etc. I'm currently implementing it on Maccaroni Island, and will update within a couple weeks :D
