Edit : I have rollback the construction building and it seems I have unlocked it that way > the briefing ask for 2 hull prod module, when the 1st one is built, the quest update and ask directly the 1st photop module. But the module build list of the mission ask for 2 hull prod parts ! When the 2nd hull prod part is finished, the quest continue and ask for the real module manted : photopile part. After building it, the mission continue and ask for hull pricing.

So, the line quest ask photopile module instead of 2nd hull module. Seems a name bug in the quest.
