HO 1.0.0, AC 1.1.0.

Presumably related to the "saturation for all food is infinite" bug. AppleCore's tooltip reports some saturation (for example, HC Bacon Mushroom Burger: 8.5 shanks of saturation, 8 shanks of hunger), HO's reports different (respectively, "Unfulfilling"). Growthcraft's drinks have negative saturation and are also "unfulfilling", melon slices, sodas, and a lot of other mod "Snack"-level hunger foods are "Hearty" despite restoring .5-2.5 shanks of saturation, HC's Cherry Cheesecake lacks saturation tooltip (7.5 actual saturation shanks, 6 hunger shanks - also reports as "Feast"), all "Nourishing" foods, to the one, have .5 saturation and .5 hunger shanks, et cetera.

F3 menu reports expected saturation, for example HC:Roasted Pumpkin Seeds, with 1 shank of hunger and 1.5 of saturation, eaten at 19 hunger value, resulted in 20 hunger and 2.4 saturation despite saying they're "Hearty".

Are you playing on a server? If so, is this reproducable in single player?

Yes, and yes, singleplayer has identical issue.

Can you post your HO config and any HO .json files you're using (if any)? Use http://pastebin.com or something similar.

This might actually be down to saturation being a confusing mechanic.

1 saturation bar = 2 saturation. So the 1.5 saturation bars of roasted pumpkin seeds could actually be representative of 2.4 saturation (and it might actually be showing 1.25 saturation bars in the tooltip).

The HO "Feast", "Nourishing", etc tooltips have some weird logic to them carried over from the original mod by iguana_man.

But, still, post your config + any .json files you're using and I'll be able to take a better look.

Sure, but in previous versions tooltip worked as expected, with description near-completely matching what AppleCore displayed - e.g. one-shank foods were all "Morsel", there were "Wholesome Feasts", et cetera.

Everything seems to be working correctly. The HO tooltips are chosen based on the ratio of saturation:hunger. The actual saturation restored doesn't matter, only how much it restores in proportion to its hunger (which is how saturation is defined in code, it is a modifier that gets multiplied by the hunger).

So, the HC Bacon Mushroom Burger has a saturation modifier of 0.6, while the rest of the HC burgers have a saturation modifier of 1.2 or 1.6 (HarvestCraft is incredible inconsistent and arbitrary with its saturation values). This means that it is unfulfilling, at least in comparison to other foods with the same hunger value. And small snack foods with more saturation than hunger are hearty, at least in comparison with snack foods that have a lower saturation:hunger ratio.

Also note that default HarvestCraft (and vanilla MC) saturation values are insanely high in general, and that most high hunger foods easily surpass the max saturation it's possible to have (10 saturation bars) and therefore will only show the 10 saturation bars in the tooltip.

I was correct about roasted pumpkin seeds: 2.4 saturation appears as 1 1/2 bars of saturation, so there's nothing weird going on there except the internal units being confusing (same thing with hunger; 1 hunger = 1/2 hunger bar).

I would assume in previous versions, you were either using useHOFoodValues=true (which would make saturation both much lower and consistent) or some non-zero value of foodHungerToSaturationDivider (which would force saturation to be consistent across the board and directly related to hunger restored).
