Upon Taking damage when beginning to cast Howling Gale and consuming both charges with <Wind Archer>, it fails to summon and Howling Gale first appears to be charging but does not increase charge count and becomes permanently unusable until disconnected from server and relog.
This occurred 3 times to me, the first happening when farming unripe/ripe wolfruits (details unsure if I was hit by a birdshark), the second during a Hard gollux run after getting hit by black breathe (ability was unusable for the whole run afterwards), and the third happening when far right statue of pink bean chaos knocked backed me.
Dying nor changing maps fixed this until relogged.
