This happened to me right now, at the Island Monastery at River Severn. I raided this location before, but couldn't finish the raid since I couldn't bring all the goods with me. Now with the second time I'm raiding it and getting al the loot it doesn't show as a finished raid

@ubistorm Sorry for the late reply. It was in the description the entire time I've had the shield, which is minutes before I posted this.

The shield that you get from Reda after the first 10 contracts has a bugged description. When you look at the details, it doesn't show the bonus ability damage.
