Issue Description

As the title says, I cannot suck blood as a vampire on any version of Vampirisim past version 1.4.9. The fangs icon still shows up and V is keybound only to the bite attack and no other action, but I cannot suck blood at all no matter what I try (sneaking, attacking/sneaking from behind, holding a glass bottle, holding an empty blood bottle, consoling my hunger to 0). I can still bite entities that you can't get blood from, like zombies (and chickens for some reason), but I cannot suck blood at all, whether it be on vanilla entities (like cows) or on MCA villagers (which I've added to the vampirism_blood_values txt file as instructed).

Reproduce Steps

Run any version of Vampirism of 1.5.0 or higher, try to suck blood, be sad and hungry.

Additional Information

Did something change after version 1.4.9? Is there something special I have to do to feed now? If I run version 1.4.9 it works fine.

Have you tried holding down the biting key for a few seconds while looking at a creature?
On version 1.5.0 and higher a delay has been added; sucking blood is no longer instant.

Thank you! That was what the problem was. I've been trying to figure out what was wrong all day.
