When I use my trident with riptide, most of the time it simply throws me in the direction I'm looking without using durability, dealing damage or displaying the animation and sounds. The no durability part is not because it also has unbreaking III as I got one without and it still did this.

It does sometimes work properly as intended but only after repeatedly trying to do it.

This issue could very well be to do with the server I'm playing on as it usually runs at about 5-8 tps (we're trying to fix it), or one of the plugins it has, as in singleplayer it works flawlessly.
