Hi MyGodness! I wanted to report a possible issue with the new Montana expansion for More American Cities (Early Access). Yesterday, my game crashed when I crossed the state border near Crow Agency. Today, I created a completely new profile with MAC as the only active mod, with no other mods installed or enabled, to rule out conflicts with other mods. When I selected Billings, Montana, as my starting city, the game failed to finish loading and produced the following console errors: - "Item duplication detected!" - "Failed to merge new sector data!" The issue seems to be related to the new Montana expansion, possibly in the area around Crow Agency and Billings. Other MAC areas, such as Texas and California, have been working without any issues. I wanted to share these findings in case they help you identify a possible issue with the new expansion. I can also provide screenshots of the errors if needed. No road tríp activate. Thank you for your work on the mod!

MyGodness

Thank you for the report. We already found this one and it will be corrected for the public release 🙂

MyGodness

Yes and no. It depends on the map in question. The best way to know is to test it.

Hey MyGodness, just wanted to say thanks for fixing the crash! I was travelling west through Montana, and got this hard, repeatable crash. I ended up having to teleport my truck to Bozeman MT, to get past it. For those asking about map combos, I'm using MAC in a large combo, with Reforma, Better Arizona, C2C, Alaska NTTF, Promods Canada, Discover Ontario/Quebec and EMMN. It all works fine... :D
