Milk Cows... I mean delete buckets....

What I expected to happen was...:
I expected to get a bucket of milk when I right clicked the cow with my bucket.

What actually happened was...:
When I right clicked the cow with my bucket my bucket disappeared! Worst part: This was in hardcore!!!!

Steps to Reproduce:
I don't know if this affects it, but here we go!

1. Generate random terrain in hardcore.
2. Receive bucket.
3. Find cow.
4. Milk cow.
5. Watch bucket disappear!
6. If this did not work try using a breeded cow, not sure whether my cow was breeded or not. I have a lot! Thanks in advance! Good work you've made, so much progress in such little time! Loved this game since the beginning! -NinjaKingRo
