1. Map/Scenario Editors: Game always saves data to the default game folders!

   If you are making a map/scenario, remember that the game never saves files to your mods/ folder! The game always saves data to the default game folders! Always copy all generated data from the game files to your mod files.

5. How do I change the background and scale up the world in the Map Editor?

   Main map and the map in the MapEditor within the template are small and lack clarity. I would like a large, high-resolution map, similar to 'Earth3'. Furthermore, when I create a province in the MapEditor and load it into the game, the province appears distorted—and this issue isn't limited to coastal provinces. @Łukasz Jakowski

8. Sent back to main menu error

   I have a mod that adds new culture groups among other things. When I try to open certain scenarios with my mod enabled, it sends me back to the main menu before I can select a country. Does anyone know what can cause this? It only happens when I select some scenarios and not others.

19. How to Create a Special Alliance

    I have noticed that there are two types of special alliances. 1. Holy Roman Empire 2. Defensive "Holy Roman Empire" type is used by Holy Roman Empire. (This makes sense) The Emperor joins the other member's wars and it can get buffs by reforming. If you make the last reform, the whole empire get united under your flag. "Defensive" type is used by Shogunate, so Japan. It's not as useful as Holy Roman Empire. There is no option to reform. But if someone attacks any member of the alliance, all members join to the war. In Holy Roman Empire, just the Emperor joins. But, I am curious that how I can add my own special alliance. I don’t mean editing the e…

20. Long loading of mod in Steam Workshop

    Hello, there was a problem with updating an existing mod in the steam workshop. The mod is about 1.8 GB in size and it takes an incredibly long time to load, despite having a fairly high internet connection. Maybe someone of you knows how to fix this problem? Previously there was a problem with a loading error, but I fixed it by changing the Changelog in the mod file. Is it worth waiting any longer? The mod number in the ID file is correct, I double-checked it in advance. By the way, if you really want to play AOH3 with music from HOI4, I recommend my mod :3 Link: https://steamcommunity.com/sharedfiles/filedetails/?id=3354002600

23. is it possible to make the game run slower

    basically I made a map of 280bc with like too many tribes, I like realism, now the problem is that it's not realistically viable to make the Roman empire or Hellas in 300 years if you don't go insane so it takes away from rp, now is it possible to make the years go by slower? I already edited the time in ages, I was more wondering if I can go from 24 hours to 36 hours or so

24. Is it possible to remove portraits

    I feel like portraits hinder my ability to make a good ancient history mod, I can't find good portraits for all the cultures I have, nor do I have imperator so I can't ss leaders there, so I rather just get rid of the portraits in general, the focus is on the ancient world and statehood, I can add symbols for the general and advisor slots, but the leader portraits annoy me(as in finding suitable portraits) I tried an CK2 mod for the ancient world, the portraits look ok, but still not great, I rather just get rid of them
