So on my Lok Revenant Grenadier, the grenades of where they are launched from are a bit off from the hp fire. It fires a bit off to the left. I'm just using the common mortar launcher at the moment, since I switched from the Packard Mortar Gun that I was using and even still it's firing a bit off center. Been trying to find the odf that contains the hp fire values. I know I've seen a few around.
