Spellslinger doesnt trigger any spell

After obtaining the wand with the "spellslinger" ability, I transferred the "living bomb" spell into it, and it just disappeared. Now the bar fills up, but no spell activates. I tried different spells, different wands, unequipped items, relogged, etc.

same issue spellsinger don't work for me....
Erengy increases to 100% but the soketed spell is never cast

i do have the same issue. it stays at 100% and doesnt trigger any spell. is this buggy or do i something wrong?
