UPDATE: This issue has (as far as I can tell) been fixed in Duviri Paradox, Hotfix 14
What is the bug?: Zephyr's tornados stop absorbing and redirecting damage after receiving elemental damage once until the end of ability duration or recast. Most of the time, the bug persists until the end of the mission. Tornados continue to work normally if it only receives physical damage. Sometimes only one tornado is affected, while the rest work. Has happened in all 8 missions of testing with Zephyr (3 in SP Ani, Void. The rest in simulacrum)
Reproducing bug: I am unable to find the definitive cause of the bug. I was playing solo in all the missions where I noticed the bug.
However through various tests, it seems companion projectiles which deal elemental damage, namely Synergized Prospectus, may be the most common cause of the bug. Have seem the bug occur while using Panzer Vulpaphyla with Viral Quills, but this could be a coincidence. Cannot recall bug having happened when no companion was present.
