Yeah there probably is some level of corruption but if it's not affecting my game play, I can ignore it.
Invisigoth's post showed up as I was tying my reply, but I want to second what she said. In my experience, TS2 bugs often don't affect gameplay immediately. For example, problems I had in the past included one Sim having a corrupted memory, which spread through the neighborhood as gossip, and I did not realize it was a problem until numerous Sims were "infected" with the bad memory. If you are concerned that there is corruption in your neighborhood, you are better off taking the time to fix it NOW when your neighborhood is smaller rather than later when it is larger. If your neighborhood is relatively small, it might not be a bad idea to take the time to clone the Sims you are attached to and start a new neighborhood. You can use SimPE to re-establish the family ties of the Sims you cloned. I believe there are tutorials in Peasantry on how to do this.
My advice is to look at the hacks available on this site and install all the critical and (very) important fixes. If you have not done so already, do take the time to delete the extra tour guides. You can also use the lot debugger to perform periodic game maintenance, such as deleting neighborhood gossip and clearing memories from dead Sims.
I never would have thought moving an occupied lot would damage things. Seems very irresponsible of EA to not warn you about that while you're doing it.
Yes, that is quite an understatement. I would go a step farther and say that it is moronic of EA to include a feature that is so obviously broken.
