But there are other things that you normally wouldn't think would spoil like sugared dough, cornmeal, raw sugar, etc.
Raw Sugar spoils? Gee I didn't know that, thanks for the heads up. You know what else spoils? Cans of energy drink. They turn into spoiled drinks instead though.
The taming situation is wonky and inconsistent with the way the game handles a full inventory in other situations. Let's compare it to what happens if you wrench a car and an unexpected engine drops:
First the game tries to place it in your inventory, if there is a free slot available.
Then, if inventory is full, it tries to place it in your toolbar.
If the toolbar is full too, the engine drops to the ground and can be picked up still, if you free some space.
The animals not so much. The game will try to place them into your inventory, but if there is no free slot, the animal is lost, even if it shows an icon of picking it up in the bottom right hand corner.
Of course I always have free inventory slots available.
Yeah, not happening in my world. But now that I learned it the hard way, I try to free some slots, more than one, because with the animal hitboxes, it's easy to whack some shrubbery and fill up that one precious slot with plant fibers first.
Not sure the amount of work required to fix this though, since picking up engines is part of the vanilla game. Even though I think picking up animals should check at least for hotkey slots, I'd say the priority for this is low, because you can avoid this by preparing. You have to know about it though, so I suggest adding a warning to either the whip or to the quest text of Husbandry Basics 1/4.
