Master of Orion – Patch Notes v55.1

Greetings Explorers,

Today we released an update that addresses certain issues present in the last build. Read on for the full list of changes:

  • Improved Performance: Turn processing has been greatly optimized. Turns now process up to 50% faster and scale linearly as the game progresses, making long matches in huge galaxies more playable.
  • Fixed a bug that caused the MIRV missile modifier to act erratically.
  • Added most bug fixes from Spud Dastardly and WhatIsSol Mods.
  • Fix for Gnolam doomstar design attempting to use the “Heavy Mount Modifier” for missiles. It has been modified to use “Heavily Armored Missiles” instead
  • Fix for AI making lopsided trades in order to get trade treaties from the player
  • Fix for Leader bonus not being added to defender’s armor value
  • Fix for incorrect population growth ratio
  • Fix for the inability to abort combat under certain circumstances
  • Fix for defender armor using the wrong constant
  • Fix for Leader bonus not being calculated correctly for the attacker
  • Fix for fighters consuming ammo too quickly and returning for resupply too often
  • Fix for attacking race's trait (beam defense was being added to the defender’s beam defense)
  • Fix for Leader bonus being calculated incorrectly
  • Fix for static defenses not healing
  • Fix for Leaders’ total cost re-displaying fleet upkeep costs
  • Fix for Leaders’ ships ground combat bonuses not having any effect
  • Fix for missing "ship repair" Leader bonus
  • Fix for missing "spy experience" Leader bonus
  • Fix for several malfunctioning achievements

Enjoy the upgrades and Conquer the Stars!

Please Note: If you are playing with mod's enabled and run into issues with the new version, please patch to the 54.11 - Revenge of Antares branch to continue your game with the old mods.
