Re: Extended shipbuilding times
I'm noticing the longer ship build times too, so I decided to test it by creating two new games, one in 5.42 and one in 5.52. In both games, I started conventional with all other settings default, including the date (1 Jan 2025), and gave myself:
Shipbuilding tech 560
Propulsion up to Ion Pulse drive and 0.8 efficiency
Cryogenic Transport
High Density Duranium Armor
Cargo Handling System
(along with prerequisite techs for these)
I then designed a simple colony ship with 10 cryogenic transports, 20 commercial IP engines, 3 crew quarters, 3 cargo handling systems, and the rest default, weighing in at 51,650 tons.
I created a 65000-ton commercial shipyard with 5 slipways, and set it to build 5 of them.
Version 5.42 completion date: 22 Sep 2026
Version 5.52 completion date: 6 Mar 2031
If there's some dispositive difference in my two basic setups of which I'm not aware that could occur with the default Terran Federation setup, my apologies. But it definitely struck me in my ongoing conventional-start game that my first simple troop transports (for engineer brigades) are taking 4 years instead of 1.5 or 2.
Hope that helps, and apologies if it's duplicative or otherwise unhelpful.
