[excalibur animation bug] Cannot Attack or use Skills

[Ritchel]

Happened when i was using his last skill on and off, as you can see the skill is still activated but it doesnt continually consume energy 
i cannot remember how it lead to this but i recall switching to mellee mode alot while activating the skill.
heres a screenshot when it happens.
