severe strongbox bug leading to no attack/skill or any action at all

hi i did a lot of strongboxes in maps but i foundout that sometimes i after i open a strongbox i can't attack, skill or even open a portal at all, the only solution is to change char and login back, it's all for the debuff that didn't let u attack for 2-3 sec but after it expire it continue to persist or bug that i can't attack at all
