jsalemi - mind telling me what attraction markers are and what they are supposed to do? All I know about them is that there is an option to delete them on the lotdebugger - which means they often need fixing! What do you lose if you delete them when there isn't a problem?
EDIT - search is your friends - Pes says
" They have been known to become corrupt, causing your game to crash or error repeatedly, which is why the option to pzorch them exists. As they seem to serve no perceptibly useful purpose, no harm is done by nuking them as often as you want."
This has certainly been my experience. I thought that it might eliminate the bolts that sims had for other sims, but no. Treating my hood as a test hood, I tend to nuke/fix everything every so often and so far nothing bad has happened. Anybody got some wood to knock?
