Hi, I have just began using SimCity after a long time of not using it. I installed the newest NAM (V29). There is a very odd problem, which I have not seen ever before. Here is what happens: when I use the bulldozer tool, the smoke/debris that appears is represented by FLYING RAILROAD TRACKS!!! It worked fine before I installed the NAM. I am using SimCity 4 Deluxe on a MacBook. I don't know if this issue has turned up before, if so, I couldn't find it. Please fix it.
