(strength bonus) strike bug
 

Recently I was building a character weapon using the (Strength bonus) Strike power and I noticed a weird bug. For calculation purpose I added the Mighty PF and suddenly the system started adding the power ranks to the PL calculation.

Since the only purpose of this power is to calculate how many ranks of strength are affected by a certain extra the presence of Mighty is seem redundant.

Any way the ranks of this power shouldn't be calculated for the purpose of determining PL.

You shouldn't be able to add "Mighty" to the (Strength Bonus) Strike power, you're right. Assuming you don't do that, is Hero Lab doing anything wrong?

Or does it just behave oddly when you add the Mighty power feat, which is something that shouldn't be allowed anyway?

As long as I don't add it everything seem to work fine, the problems came in only when I add it (which, as you said shouldn't be allowed).

OK, thanks for the clarification.
