Hi! I'm trying out Alternate Entities. I've moved a few files around to get it working and I think the only thing left is fixing the spider.

Here's Alternate Entities : alternate-entities-v1-4.zip

Here's my moved-around version : alternate-entities-modified.zip

Is there something I moved wrong?

Thanks!

(Also claim my bounty please)

Spiders probably shouldn't work in the first place. This screenshot is with OptiFine.
