What the players have learned today:
The devs DO NOT play their own game. Long suspected, now without a doubt confirmed. I have no doubt at all now. None.
The devs don't want the players to have fun.
A Server Error when trying to apply an experiment effect on these reward FSDs indicates to players of a coding issue & a feature -- previously working on all modules purchased or granted as rewards from CGs -- not working as intended / broken / to be fixed; and the lack of such an error on the previous reward FSD and all other modules we buy indicates intended behavior. Instead of admitting that and allowing for fun & options for the players, the devs jump through hoops to explain it backwards and justify blocking it.
Similar behavior was seen in May when Odyssey released "complete" about 2 weeks after the alpha test closed, and has take 6 months of focused fixing & patches to make it decent.
Mitterand Hollow be "fixed" next then, yes?
Without being able to add the experimentals on these three reward FSDs, they've given me no appreciable gains in jump distance over simply engineering them myself Long Range 5 with Mass Manager, as I've done for my entire fleet of ships over the years.
Having these reward FSDs and adding an experimental effect for that extra, otherwise-not-possible boost to jump range made these rewards special and worth the competition of that CG.
(Sally, I'm sorry you're caught in the middle of this. Let's not ever shoot the messenger!)
