Unable to complete a menagerie fight.

I logged in on a standard character to test some stuff and went to the menagerie for a craft of add prefix/remove suffix on a 6L bow.

I killed the monsters but the fight doesn't end. There is no crash, my character is simply stuck in the arena and I can't get my item back.

I logged out/logged in again to retrieve the item and the game considered that I failed the fight. The beasts disappeared.
