I don’t think what I’m asking for is all that difficult, really.
The heatmap issue shouldn’t be too difficult a thing to solve. I personally would have no idea how to do it, I’m not a coder of a game developer, but it looks to me like all the pieces are there, they just need to be assembled correctly. Or they could go the easy route and update the in-game codex to better reflect what actually goes on instead of leaving it misleading.
You would need to know the exact location of every single piece of bio on the entire planet to generate the requested heatmap, that's all, simple really, only a few trillion entries!
