This one is "not". incorrect there are two separate but equal ways to produce SB Modules one is on planets the other on Shipyards, though the +2 should be in both or neither description.
If this one technology gives the ability to produce Modules on both planets and shipyards then just saying "Produce Modules" once should be sufficient since there is no way to get the ability to produce Modules on just planets or just shipyards.
I find it difficult to understand why you would try to justify repeating the exact same text twice. If you believe that they represent 2 separate and distict abilities then the text should be modified to more accurately convey the abilities that are gained.
Because it has been there since at least the change to planet based modules was enacted.
As for modifying the text they have actual bugs and other things way more important than a miss phrased pop up to work on.
I say this because many posters here, on discord, and on Steam report bugs and crashes but you are among the 2 or three posters mostly on this forum that point out spelling and semantic errors. this is also one of if not the least trafficked forums.
Add if this double mention is across the board in all languages they will not only have to add what you want to the English build but all the others as well.
As you are the only one who has pointed this out it must not confuse many other posters.
