Hey, Champ. Thanks for helping me regarding this issue. To answer your question about which mods I've been using, I've been using a variety of mods, but for the sake of resolving this issue I have limited myself to the three base mods (Cataph's Kraka Drak 2.0, Community Modding Framework, and Crynsos' Faction Unlocker+) and yours (Climate Mitigation) but have found myself crashing all the same once the 1st level of the building chain is completed. And to answer your other question, I haven't tested the other provinces, as I'd assume I'll crash the game all the same if I tried the building chain there.

Just tried the latest version and found myself with the same issue. In the efforts not to undo all you've done and corrupt the games of the rest of those using this mod, do not trouble yourself too harshly with resolving a bug only I've (or a few others) been having. All in all, thanks for your help and I'll do some other testing to see what could be causing this.

I assume this is the right place to put this but after finding myself unable to fight a battle with a particular army due to the game crashing I found that the cause was the Rangers of the North unit. For some reason this unit is causing crashes of my game both in Custom battles and Mortal Empires. I have removed all other mods bar the ones needed for this (so Kraka Drak overhaul, Community modding framework, the faction unlocker, and this mod) but the crash still occurs.

I'm not sure if there is something else that I have overlooked but as far as I can tell it is just that unit that is causing issues. Not massively problematic for me since I can just not recruit them but it is a problem nonetheless.
