The spells for the magic bow dont work like they should- the game detects it as a regular bow. Shooting it will just shoot a regular arrow, even if a spell arrow is selected, and if the spell inventory is open on the hotbar it will consume the arrow used as an icon for the arrow_regular spell. Switching the id to something else fixes that issue, but the spells still don't cast.
Changing the magic bow to work as a quick cast and changing the id for arrow_regular to something else allows the spells to work, but they do not shoot based of a bow draw value. Is there any way to fix this? Not sure if anyone else has this problem either.

Are you pulling the bow all the way back like you would to fire an arrow normally?

Yes, i am

Seems ok on my dev server- have you made any modifications to your configs for the bow or spells?

I just did

/mgive magicbow
/mgive arrow 64
Hit Q
Select the poison arrow
bull bow back, fire poison arrow

Tried that, didn't work- same type thing happening. I hadn't modified configs relating to the bow or arrow spells at all, but I reverted to all default configs by regenerating the config files and still had the same problem. Tested it on a friend's server and it worked for him too. I'll attach a video of the bow in-game and a screenshot of my plugins list. Starting to wonder if it'd be a plugin incompatibility, but not sure what plugins would interfere.

Nevermind, I fixed it- had to reconfigure multiverse and change the world names around.
