same spell 2 times in skills build

somethin very strange hapand to me last night when i was arranjing my spells

i dont know how , but somehow one spell got covered with a circle fire worp effect , i thouth it was something behind , so i dont care much .. but when i put a new spell , the spell covered with the effect becomes the same as the one i just put ...

in the end , i had 2 spells of the same kind in the skills bar

phoenix fire spell

i freaked out , didnt even took a screen shot , so i could show
i tryed to do it again , so i could learn , but couldnt anymore

i have no clue what i did to make that hapand

i did that in team arenas

anyone know anything about this ?

Sounds like a bug. Sometimes strange things happen when you're switching around your skills.

Although, there are a few skills, like Arcane Echo, Echo, Arcane Thievery, and Arcane Mimicry, that will allow you to have multiple copies of the same skill on your bar.
