I only started "playing" SimCity 3 weeks ago, so I can't tell you if it was a bad lot or modd that caused the problem. As a matter of fact, I'm still reading your forums to learn the game. (Great site by the way!) I had a new city with apx. 50K sims with light residential, commercial, and ID, zoned. Heavy street traffic, went to roads, then avenues,..... still congested. Well, time to experiement with MT, using a monorail system. Configured the monorails around existing structures..., decieded to change monorail direction. When I bullldozed the rails, a med-center was slightly to the right of a rail section. "Dozed" the center several times, but it came right back. Tried to rezone over it, dezoning it, & rebooting computer. Nada! So I destoryed the surrounding buildings and continued outwards, until program allowed me to destory it. I noticed the med-center had a darkish brown color to it, as if abandoned . The only modd I'm using is the Network Addon Modd. I think you guys call it "NAM"? Is that right? Is it a lot or modd problem? Or just a game quirk? Thanks System specs: SC4D-RH P4 2.80 Ghz, 2Gb DDR Ram, 800 Fsb, 260 Gb Hd, XP Pro
