I downloaded the latest version thinking it was just going to be balance changes...and wow, everyone has nice, shiny new models! Balance is far better than it was before. The Replicators still seem a bit overpowered but at least they aren't invincible now.
I did run into a level 10 replicator support capital that had shield mitigation of 92% (almost invincible with its shield restore) but that is easily fixable by making its mitigation value the same as the other capital ships. Every other capital has maxMitigation StartValue 0.650000, but the CAPITALSHIP_SUPPORT_Replicators has maxMitigation StartValue 0.700000
Edit: fully upgraded, all the replicator capital ships are still going up to around 90% mitigation (even outside their culture). I was able to bring one down in a battle, but I had to focus my entire fleet (and bombers) at it. Unless you intend for the replicators to be a super race that everyone has to team up against, I would suggest lowering their capital ship mitigation (the smaller ships seem fine).
Also, I can confirm that the values for the Norlamin mass upgrade techs are broken again. Both RESEARCHSUBJECT_SHIPMASSREDUCTION0_Norlamins and RESEARCHSUBJECT_SHIPMASSREDUCTION1_Norlamins are now adding to the ship mass instead of lowering it. The researchModifier perLevelValue for modifierType: "MassReduction" should be negative.
