Assailum and Snipe is still bugged

I just started a new bleedbow glad and I just found out that snipe work maybe once every 5 times. The other times, the arrow is just not fired. I searched on this forum and apparently, this bug has been in the game for at least a year.
This bug makes Assailum totally useless.

Have you tested if it works if you deactivate an aura?

Do you have enough mana to trigger the skill in question at the time you release your charge?

Well, nevermind. You guys are right. It was a mana issue. Sorry for this post.
