Hmm, I'm not sure I fully understand. So, when your stomach is empty, and you hunt something, it doesn't spawn the food object for awhile?
There is an intentional delay timer based on food size compared to stomach size, shown by the 'Hunting...' overlay that ticks down until it continues on and finishes the hunt (spawning the food object). Depending on size, that can be anywhere from instant to 5 seconds, but I'm guessing that's not what you're referring to?
If you could perhaps grab a screenshot or two, that might help.
If it's just the regular hunting delay based on target size, then that's an intended part of the game, not really a bug. But if it is taking a full minute for the food objects to spawn in, and you technically get the food (in your stats at the top) before the objects show up, then that does sound like odd behavior.
Unfortunately, I've not ever seen that happen personally, and have not been able to recreate it from how it was described, so I'm not sure if I will be able to do much about it for now.
