Version 4.1.1 is now available. This is a focused follow-up to 4.1 aimed at late-game performance. The most noticeable change is reduced lag when ending a turn in a large, late-game empire. We have also fixed a handful of crashes and made it harder for rivals to culture-flip your planets.
Engine
Fixed late-game lag ending a turn due to stat calculations when colonies changing hands.
Fixed late-game lag related to fleet range calculations.
Colonies that lose their sponsor during a rebellion are no longer left stranded, and any stranded sponsor links in an existing save are repaired on load.
Fixed a crash when mousing over the key terms in the Energy resource bar tooltip.
Fixed a crash in multiplayer when a completed mission referred to a ship that was not in a fleet.
Gameplay
Influence is now much stronger on a planet's own tile and the six around it. A planet is much harder to culture-flip unless the competing source is close by or vastly stronger. Borders elsewhere are unchanged, so empires still cover the map as before.
