Normally in one's inventory, you can click on an item, and it will follow your cursor until you put it in a slot. For me, that does not work. I have to drag it with my cursor instead, creating issues in crafting, as an example. Also, when I want to drop a few items into a certain slot and keep the rest in a different one, that is bugged too, in a way that does not allow me to do so. Fixing this issue would be helpful, as playing a survival game is very different.
