This might be a trivial question, but some of mechanics are not very evident in the game.
The issue is thus - looking at a research screen certain mod costs 5 cosmite. Looking at unit modification it costs 6. For a new unit it costs 5 still. I remember applying the same mod to an existing unit at 5 cosmite cost previously.
Obviously there is some sort of modifier or mechanic that influences cosmite cost of applying a mod. But I can't find any hints as to what triggers the higher price and if the modifier can in any way be manipulated. It is a frustrating bit of opacity.
