Load Order - ATS v1.55 Map Combos (Updated 28 Jul 2025 - ProMods Canada)

[LugNutz]

A mod which they will be banned for if they respond to your question.
It was removed for a reason.

Can you PM me on what the mod in question was that was removed. I know what I meant to put there, and its a mod thats listed on page 1 of the load order in that spot, so thats why we are confused as to why that mod was removed, unless I put the wrong name or mod in that place when copying the load order. Just wanting some clarification, so as not to have it happen again. Thanks.

@Vinnie Terranova Lugnutz is correct, the mod referred to is listed in your load order and has now been removed.

Reforma Flares Fix (FOUND ON STEAM WORKSHOP)
Reforma Sierra Nevada
Reforma
Reforma Mega Resources
More American Cities (California)

Sierra Nevada and MAC California can work together?

[Azuirele]

They can't, the area around Yosemite National Park would have conflict if try using both together

Worked fine for me in 1.54 if you put More California Cities below Mega Resources. I haven't gotten that far in my 1.55 load order yet (started a new profile) but the map is not showing obvious conflicts.

@omnibot Many map mod conflicts don't show visually through in-game map, but rather through in-game errors, such as invalid texgen value, failed to merge sectors, etc, which lead to CTD when driving in certain areas. It doesn't show any obvious conflict like broken road, missing prefab in world map, doesn't mean it "works fine" as well.

P.s: The last time I tested both mod together, I got a CTD around Palm Springs (I also use the main Reforma). This is around couple weeks ago of course, and wasn't even close to Yosemite National Park, but I removed MAC and no more crash at the same spot, hence I won't change my statement that both mod are unstable to be used together.

[Vinnie Terranova]

@Azuirele I don't have any CTD's in or near Palm Springs... But you said that you had a CTD a couple of weeks ago. With ATS v1.54 or 1.55? Besides that, in the past couple of weeks a lot of map mods have been updated.

It would be nice if you would have provided a game log. Because saying that you had a CTD a couple of weeks ago is not very helpful.

I've driven it extensively in previous versions and have encountered no errors. OK? Since you haven't submitted a game log, we don't know what other mods you're using that might conflict. No need to get snarky about it.

Also, your initial post indicated conflicts "around Yosemite" but then you admit the crash took place near Palm Springs. So how do you know there are conflicts near Yosemite?

@omnibot When I say testing, I explicitly mean only those two map mods + reforma mega resource are loaded. I'm not dumb enough to use other unnecessary mods when doing a test.

@Vinnie Terranova However, I will admit to both of you that I was hasty and didn't look through the whole conversation; rather, I focused on MAC + Reforma Sierra Nevada only. The test I mentioned was conducted when I tried to force delete sectors from mod files, then copy/paste existing sector from Reforma to MAC to prevent broken prefab, and load the game with this modification. This apparently wasn't good enough, as there was no visual issue, but it caused the crash around the area I mentioned above. This is my fault here, so I will claim that.

I tried your load order; fewer cities appear compared to my custom modification, but I no longer crash around Palm Springs (or Coachella, to be exact, which is a city from MAC). I have another question in this case: does this work smoothly with no error, missing prefab, CTD, etc, for the rest of the cities from MAC that are still visible with this load order? Because on GMC website, they still list MAC (California) as incompatible with Reforma Sierra Nevada (and Yosemite Valley is one area that falls into this). I would like to forward this to Marian if they indeed still work together.

There is no practical way to tell. The only way to check for CTD, missing prefabs, broken roads, terrain gaps, etc, is to drive all shared sectors (and part of all sectors that are adjacent to those shared sectors). And even then you will not have 100% garanty, because sometimes an incompatible map mod can cause issues hundreds of miles away from it's sectors.

So, that's why I decided to include the MAC mods into the load order. I cannot test it fully; I can only test it very lightly. But there are more people than just me who are using this load order. And in fact, all those people are in some way testers. If somebody finds an issue, it's just a matter of finding the cause of that issue. And it's possible that a certain issue is caused by one of the MAC mods. If that's the case, then the solution is: inform the creator of the MAC mod about this issue and disable the MAC mod until this issue is fixed.

But personally I don't think an incompatibility issue of a MAC mod with another map mod will be fixed. I think that the MAC mods are mainly meant to be used with only the base map and the official map DLCs. Not to be used with other map mods. Regarding this load order I've put those MAC mods at the very bottom of the load order, so if there are shared sectors between two map mods, the shared sectors of the MAC mod will be overwritten.

And now it's just waiting for the first compatibility issue to be detected. That is, if there are incompatibility issues. Only time will tell.
