Put the summary of the bug you're having here
What I expected to happen was...:
so I was going to infect a villager and turn him into a zombie villager then
What actually happened was...:
the zombie kill him and the villager didn't turn into a zombie villager
Steps to Reproduce:
1. put the villager (doesn't matter if he has ANY trades or not) in a minecart
2. put the minecart with a villager in it next to a zombie doesn't matter what hes got or if he has a nametag
3. then the villager dies in stead of turning into a zombie
