Calorie production drops to zero after 2065

[tessarion87]

Hi,

So, for some reason, the plant and animal calorie production drops to zero after 2065, setting off global famine (fortunately, I had enough Contentment built up that I was still able to win the game).

Here's my event log:

Thanks for the report, someone else is having a similar problem. This is kind of hard to debug so I just pushed out an update that will include more info in the JS console/end-of-game summary, so if you happen to run into it again please update with the latest logs. But I'll see how far I can get with what you've provided already. thanks!

In my experience, this happens when there's not enough spare land (or something during the land calculation goes wrong?).

Here I was at 93% land used. (Pie chart seems wrong, I think the number is what counts)

During the next cycle, famines appear.

Indeed no more land is given to the processes producing food and other stuff.

May be related to #259 .

scanning the steam discussions, there seem to be people with a similar issue in even the steam version of the game: https://steamcommunity.com/app/2071530/discussions/0/4356745048752661660/

Thanks for all the details. I have a fix for the pie chart issue and it does look like this particular production drop is related to maxing out land usage. My guess is it's related to the algorithm that determines how to allocate a resource across the production processes when there's not enough to meet all of their requirements. I'll keep investigating.

[frnsys]

Ok so I've managed to improve how the production planning algorithm works under constrained resource conditions. My setup was to implement Remediate and Protect Ecosystems and Expand Nature Preserves which gets land use up to 100%, so that reproduces land being the limiting factor.

Prior to this these were the production results: Fuel: produced=27.1, demand=108.4 Electricity: produced=4.8, demand=31.9 PlantCalories: produced=264.2, demand=377.4 AnimalCalories: produced=78.9, demand=86.3

With the new algorithm: Fuel: produced=32.5, demand=108.4 Electricity: produced=11.2, demand=31.9 PlantCalories: produced=256.6, demand=377.4 AnimalCalories: produced=86.3, demand=86.3

Not a drastic difference, but still better -- all animal calorie demand is met, for example.

But otherwise this is expected behavior--production is going to be limited if you don't have enough resources.

From the other reports I've seen the case of calorie production dropping to 0 is likely because of a fuel shortage (b/c of land usage probably) which then means there's no fuel to produce food with. I think this change will make that scenario less drastic (i.e. hopefully not plummet calorie production to 0).

I'll make another small UI change here to communicate more clearly these shortages and their underlying causes.
