Custom modpack crash

Hey everyone i wanted to put together my own modpack for myself and ive run into this error stating its missing the owl egg?

If anyone could point me to what its wanting it would be greatly appreciated!!

Okay i thought i had this fixed but im still receiving an error from the missing owl egg

sorry i dont know how to post a .txt  but ill try to shorten the error report to the actual error im getting

I have tried the newest versions of ender io and a few older ones as well.

java.lang.NullPointerException: Houston we have a problem: 'Item item_owl_egg is unexpectedly missing'. Please report that on our bugtracker unless you are using some old version. Thank you.
