There are changes as of 1.22 in that everything heats up relative to stack size now but once you've heated the whole stack the temp shouldn't reset back to 0. If it is you've either found a bug or have mod interference. I personally think the change is a bit harsh, but you shouldn't be burning 6 black coal for every single flint. I believe you can fire flint in a bloomery, just cook enough for your first bloomery in the firepit and then use the bloomery. Not ideal, but a workaround if you're having issues.

Sounds like you're doing a lot right, food tends to one of the early game hurdles new players have to overcome, becomes much easier with a bit of experience. Biggest tip is to make sure you're making meals of all your food, either in the cook pot or using the fireclay oven to make pies. As stated above, this significantly increases the satiety provided by the ingredients and meals will provide you with a pause to you hunger drain. If this is something you are already doing and you are still short on food, may be time to grab a few spears and go on a hunting trip or travel a bit further for foraging purposes. With the fishing update bush meat can now easily be converted into fish which allows you to make meals and is a better bang for your buck food option. Personally, I have a forested area near my base that is always full of wolves. Every 10 days or so I go kill a few and use the bush meat as bait, can easily bring in 30-40 fish meat in a day. Raccoons and foxes are relatively easy kills for bush meat, bears are great if you're a bit more adventurous.

To my knowledge they won't eat until they have grown up, they won't die from starvation.

I know what you are talking about, you can break them down in a crafting grid with a chisel into gold or silver bits. To my knowledge, having played through the full story as of now and spent far too long looting ruins, that is the only location they are present. I don't know if the treasure/monsters respawn after a certain amount of time though (I believe the RA does).

Before loading into your world on the far right there is a tab that allows you to edit or delete that world. If you go into the customize tab you can adjust the world settings before saving and starting the world back up. It'll be the first option under the Temporal Stability tab. It can also be turned on/off in game with the command /worldconfig temporalStability [false|true] and then restart your world to have it take effect, noticed it was a bit finicky though.
