Items won't go into inventory and will drop over and over

So I went to collect some crops from a village I found and when I broke them they wouldn't go into my inventory and keep repeating the drop animation. My inventory is not full either and I tried waiting a few minutes but it still happens. Also any items dropped on the dirt cannot e picked up even after breaking it or being pushed by water. [Update:] So now I can't collect ANYTHING that's mined or dropped. I had already been playing for a half hour before this issue began so I'm not sure what caused it.
