When i drop an enderite item it doesn't seem to be effected by gravity at all.

Demonstration: https://youtu.be/gxqQdRN-Vkk

I tested dropping items from other mods and they were normal.

tbh i really like this lol it makes sense, im having the issue to but id like to keep it that way haha

To be honest yeah, it's actually kinda cool.
Stops you from accidently losing your items in the void!

EDIT: Maybe it was intentional

It is indeed a fully intentional ability of Enderite items.^^
