The Warp Stone renders on the left hand, and continuously spams the sound when holding rightclick while never actually opening the menu. Tested using Waystones_1.12.2-4.0.20 & vivecraft-1.12.2-jrbudda-6-alpha7. Probably happens as the mod registers the warp stone as a bow.

Won't this implementation cause a desync between client and server behavior?

I haven't tested it, but I don't think it should be an issue since technically, the client can open the waystones gui at any time (the charge-up is not enforced server-side). Worst case it may play the animation for other players.

Though I'm not sure how the Vivecraft server deals with the bow things, so if someone wants to test it and there's a problem, I can see if I can get a server-side Vivecraft detection in as well.
