I have a strange issue where my commute time graph just doesn't make any sense. While growing my mainly residential/commercial city of over half a million, commute time went between 0.5 and 1.5, which seemed like a reasonable number of hours. At some point, I installed the NAM, which improved things a bit. Next, I made a neighbor city with a few ten thousand industrial jobs to support my main city, and then went back to the main city. Here's where things got weird. Commute time started to increase as people got jobs in the neighboring town, but commute time went from around 1 all the way up to about 30. It's almost as if the scale on the graph has changed completely (from hours to minutes). The graph just looks really weird since I have this huge spike after I built that neighbor city. The main city is still running as normal, with no major abandonment issues, and has continued to grow to 800k people. Any one else run into something like this?
