I'm trying to learn DW... In the Akula (haven't tried the other subs yet) I can't seem to assign targets to my torpedoes/missiles. Weird thing is, I was doing it earlier today and now it's not working. It's not the game's fault, I'm just dumb and forgot how to do it right... I looked around the manual but can't come up with the answer as the section on the Akula's fire-control merely states something like 'this is where targets are assigned to weapons'. I've got all auto-crew off and I'm trying to learn TMA so I plotted my solution, selected it in the little drop-down menu but when I click on a weapon's number, nothing happens. And it's not like I'm trying to fire a land attack missile at a sub, I'm certain (checked with 'show truth' when I realized it wasn't working) that it's a Victor III and my solution is spot on. What am I doing wrong? What prerequisites are to be met before a contact can be assigned to a weapon?

Oh and also, I tried a bunch of times but can't seem to wire-guide torpedoes either. The manual says very little about this and I couldn't figure it out.
