Was it custom recipe, and what station was it from?

it was a custom one

stove

We ran around and beat on each other to knock our health down last night, and ate a few different things I had cooked up last night. They all behaved as custom food normally does when you eat it. They filled our hunger and got our health back to full over a short time.

Were you missing health or stamina when you ate the food? If you're not missing any, you won't see anything other than your food fill up simply because there is nothing for it to add.

we were missing HP when eating the food (the food say around 2k HP and 2k Food and stamina and stuff) only food went up slowly but hp never went up.

Just tested a couple custom recipes i had from the oven and they both increased my hp regen, Do you recall which icon it was so i can check that one specifically?

We used a few icons, the meat with plate, cupcake, cake icon.

hmm I'm not sure then because those give me health regen the same as vanilla custom recipes, I'll double check them all though, maybe another mod is altering how custom food works?

do you know what the regen stat is (like always at .05hp/s or something) or is it more of a calculation based on the stat of the food (like food hp gives 2000, theres a formula of 2000 over X constant time like over 5 seconds equaling 400 hp a second)

Food/Water/Stamina will not be restored instantly, but instead increase at the fixed rate of 1.05 points per second. For a consumable with very high Food/Water/Stamina, the Status Effect will last proportionally longer.
