Had an odd experience when I hit level 60. All three of my summoning staffs stopped summoning. They're all fully charged, and show a charge being used. They go through the motions, but nothing is summoned. Is this yet another bug?

I can still summon Atronachs by hand, and the other staffs still work for for fireball, etc.

Lydia's staffs still summon the Storm, Frost, and Flame Atronachs just fine. No idea why mine are now dysfunctional. I already swapped mine for hers, and no difference. Any ideas? Sure hate to go way back to level 59, only to end up back where I'm at now with useless sticks. Thanks.

Try dropping and picking them up.

The perk Elemental Potency causes summoning staves to stop working. Did you pick that perk?
