BEERY,
I hate to tell you this but its got to be the "hardcore torpedos mod". I have NEVER had the 20 deg hook to the left problem until RFB 1.27. I have used previous versions of your mod before and this never has happened until 1.27.
I watched the torps in the external camera and here is what happenes. No matter what the input from the TDC, every single torpedo fired comes straight out of the tube and hooks 20 deg to the left.
Thanks SO much for RFB. I love the mod. This little thing needs to be sorted out though because the game is now unplayable. And yes, the unmodded game is unplayable as well so removing RFB is not an option.
I am willing to help. What are the files that make up the hardcore torp mod? I can take them out and see returning to the stock files makes the problem go away.
