I hope you're getting paid for all this. I swear you and ace have put more effort into this game than anyone else.Natural dragon (as in standard Western dragon) spawns are intended for mountain and desert regions. Dragon variants will spawn in highlands and jungle regions.
In hindsight, it was probably a mistake for me to add dragons this early and make their items available so easily, but I am working on a Fields NPC that will partially rectify this.
Encounter and map modding have been added although feature parity with source modding is not yet achieved, at least in my experience.
And if you waited for the mountains and desert areas, dragons wouldn't be in the game for years. Might as well add them now. Just look at how much vocal "feedback" was required to get fields actually worked on, and after almost five months we might finally see some of it. And that was after straight up a year of "feedback."
