Broken: Hammer of Thunderbolts?

[Warklaw]

Okay so... I am trying to create some USER content based off the Hammer of Thunderbolts. However I am noticing two things about the Hammer of Thunderbolts. 1. HL keeps throwing an error saying 'Returning' thrown weapon required (make perfect sense). 2. Even when the character has a Belt of Giant Strength equipped the 'eval script' seems not to be running to change the bonus or activate bane and thundering.

Anyone else see an issue with Hammer of Thunderbolts? Am I missing something? I have also tried marking the base weapon as Cat: Thrown Weapon... but it does not alleviate the issue either.

Note: I just re-installed Herolab... so nothing should really be altered beyond the new user file I am trying to create.
