In truss connection of HSS (chord and branch), in the interaction equation (last check) it uses the maximum ratios from each case of loading, when in interaction equation we should use each maximum ratio with its corresponding ratio. Attached a model and snap shots for the concerned checks.

It does seem too conservative to take the max in-plane moment and the max out-of-plane moment into the final interaction check since they are from different load combinations. I'll pass this along to the product manger for confirmation.
We will make the change to be less conservative in the next update.
