The case of the disappearing modules. I'll make a note.
Can you recreate this bug and do you have a save game of it?
Alpha 0.40.186553
The missions are Upgraded (Lasers), (Missiles) and (Kinetics).
When I choose the option for +2 attack (of the mission attack), it shows up on the ship profile, I move the ship to wherever I'm going next. When I next click on the ship, it is back to whatever its weapon profile was before.
I did a save when I first started the survey process, just before starting the next turn.
Where are the saves stored? And do I get it to you?
