I used Bound Mace, and accidentally repaired it. Somehow this lead to the constant Fortify Blunt Weapon effect to get stuck, while the weapon itself has vanished. This lead to an error message during save/load which i just skipped (one of those "[Issue], continue running executable?" message) by clicking yes without thinking.

Is there any way to get rid of the effect? It is not game breaking but annoying.

Can't reload a save pre-issue, noticed the problem only just a moment ago, hours later.
