While examining some of my ships I noticed that any ships with shields are receiving a "Study the Precursor Accelerator" bonus of 15% for shield strength. However, the description for the Precursor Accelerator World states "Shipyards sponsored by this world will build faster ships." There is no mention of an effect on shields.
I have confirmed that ships produced at the Precursor Accelerator World shipyard are receiving a bonus of 15% for speed.
I submitted a ticket regarding this.
