Incorrect Attack Speed?

For some reason, whenever I try to use my weapon, it always has a 1 step slower attack speed than it should. For example, my Cascade got reduced from very fast to only fast, my Bonder got reduced from slow to Very Slow, etc. Does anyone know the cause of this?
I tried restarting MC, etc, but the glitch thing is still there.

 

Pethaps you use an item that has -1 attack speed

 

Wait a minute... now I'm looking at my armour and it says my Gravity has -1 attack speed. I swear it didn't have that before the Corkus update...

 

Check your Gravity.

 

yea I just checked and now it says it has -1 attack speed :/ did something happen during the corkus update?

 

Some items are nerfed/buffed since Corkus update

Spoiler: And the worst thing is

I GOT THE -2 TIER GRAVITY
HOLY CRAP

 

Rip Gravity.
They also nerfed it's reflection and thorns.

 

All pre-existing items that were buffed/nerfed in the Corkus update updated their stats when it was released. For example, I had a 14% Walk Speed autotomised before the update, but since its walk speed was buffed, I now have a 16% walk speed autotomised.

 

Speaking of buffs and nerfs...Cascade walk speed got buffed I think :/
Got a 23%
