Sentry Error + Won't fight anything

[bluppity]

Sentrys work to an extent but they won't fight anything (even when I adjust their targets to me) at all and when equipped with something, I have to rejoin the server to see the weapon physically on them. When I add the trait sentry, I do get an error:

I'm not sure if it's because this version is 1.8.6 and I'm on 1.8.7 or something else. I didn't think there would be such a huge change between those two versions so I just assumed it would go well. Guess not. Any help would be greatly appreciated!

Update Vault + Your permissions plugin

Deleting Vault fixed this since I can't update Vault past what it is at the moment. Thank you.
