5.45 BLU action "Diamondback" activation bugged

Date & Time: Since 5.45
Frequency: Always
World name: All
Monster name: All
Class/Level: Blue Mage
Party or solo: Both
In-game time: Any time
Area and coordinates: All

The Blue Mage action "Diamondback" is activated and instantly cancelled when the player moves at the moment of activation. This is especially apparent when used in combination with the role action "Swiftcast" while moving, making it near impossible to reliably activate "Diamondback" while moving.

Before 5.45 "Diamondback" would not do that and behave in line with its description in the sense that after activation you could not move or perform any action that would lead to "Diamondback" getting cancelled prematurely.

That it not a new "bug". It is like this since Diamondback is available.
But tbh, I think it quite useful because you can deactivate it last second in case you misscklicked.

Its actually cause you have something targeted while casting it. Diamondback cast for some reason acts like you're casting it on your target so if that something moves it makes you turn to face him which counts as movement......and cancels it........
Ye it was fun figuring that shit out during a8s
