So I'm trying this mod out for the first time, having gotten bored of FF's poor improvement AI, but wanting something more advanced than vanilla FF. I'm finding it somewhat frustrating, mostly for the lack of documentation regarding most of the new civs and their various quirks, especially the Jotnar (who have apparently changed a lot from what little I read about them when they were a mod for FF - their Pedia entry also refers to them working only a 1 tile ring, not an extra ring like Kuriotates).
Crashes also seem to be fairly common, sometimes in the first turn, sometimes later. I presume this is related to AI civs and the various special mechanics of the RiFE civs, as setting them human only or locking them seems to reduce the frequency. My last game, an attempt to learn the Jotnar, also fell flat because of an AI's infinite turn (spent ~10 minutes "waiting for other civilizations.") I attempted to turn on error logging, but if it even works in the case of raw crashes to desktop, I don't know where to find the logs.
In any case, I did have a specific question. No idea if this is a bug, but I started a new game as Calabim Alexis, and my territory is freezing. Only 9 turns in and my capital's fat cross is already almost all tundra. My previous Jotnar game had this issue too, and although they seem to favor cold areas (production bonuses and their unique tundra improvement), the AI Ljosfalar also was pure ice before I had to give up that game due to the above infinite turn.
I'm aware of the climate addition, but I highly doubt the flavor of Calabim and Ljosfalar would set their climate to freeze. Is there a game option that is affecting this? I don't have the End of Winter option enabled, and the Climate I selected for the map type (Terra) was tropical.
Also, looking at the settings in-game, some of the options (like No Acheron, no Council of Esus religion) are enabled even though they are not listed in the Custom Game creation screen.
