Please explain your issue is in as much detail as possible.
Even though bonuses shown are the same (+100%), MS's build speed for some reason is slower than building the same ship in regular shipyard.
I'm not sure but it seems that the reason might be a -25% build speed technology for specific ship type not applying properly

Steps to reproduce the issue.

Here's my report for the same issue

Please explain your issue is in as much detail as possible.
I have a shipyard starbase and a mega shipyard in the same system. The both display the same +155% Ship Build Speed bonus, but the shipyard has shorter build speeds for the same ship than the mega shipyard - my cruisers have a build time of 95 days in the mega shipyard and 86 days in the starbase. This is true for all normal ship sizes but Juggernauts have the same speed in both, so the difference is something that doesn't effect Juggernaut build speed.

If I'm correct about the calculation used to determine the build speed - [base build time] x 100 / (100 + [sum of modifiers]), then the Mega Shipyard's slower time is correct and the starbase is getting an extra unlisted +25% ship build speed bonus. Is it possible the Master Shipwrights bonus is being applied twice?

I saw one even from 2020 when looking into it. Still not fixed
