Reduced the time required to build the ancient fortress of the Gamma Area.
Reduced the number of points required for some scientific research projects.
Reduced the waiting time before the arrival of the Shroud Invaders.
Reduced the probability of multiple failures in searching for ancient galaxies.
Adjusted the probability of areas generation to make it more difficult for Gamma and Zeta Areas to be generated first.
The sensor technology required by the start event is adjusted to a subspace sensor (level 3 sensor).
Adjusted the loading order of the menu so that several special-purpose edicts will always appear in the upper position.
Ancient ships will clear some bad debuffs in battle (for example, if the weapon's range modification less than -100%, it will cause the ship unable to fire weapons, etc.).
The fleet of the Shroud Invaders will have a chance to have a fleet commander who provides special effects.
Reduced the existence time of the avatars of the Shroud Invaders.
The relics obtained after defeating the Shroud Invaders now provide the building functions of three Starlight series ships.

Fixed the bug where AI repeatedly started/stopped tracking Key of Twilight special project and destroyed saved games.

New contents:
Added some small events.

Adjustments:
Reduce the time needed to study ancient ship systems.
The psionic environment research in the Beta Area can be started after the capital system is affected, and there is no need to wait for the dead pops to exceed 8.
Slightly lowered the mtth time of the Beta Area Psionic Environment Research.
Changed some events' picture.

Bugs fix:
Fixed the bug that sometimes Beta Area Psionic Environment Technologies could not be obtained correctly.
