Please explain your issue is in as much detail as possible.
According to wiki (and personal experience):
The cluster is controlled by a Fanatic Purifiers empire named "The Chosen" that cannot discover the Wormhole Stabilization technology before the mid-game year.

In my current game I decided to try No scaling as devs suggested (on top for GA of course).
In my game with 2275 mid game date The Chosen discovered the wormhole much earlier. In the Empire Timeline they met a new intelligent life in 2256 and declared war at 2263.
I checked another empire tech - they don't have Wormhole tech, The Chosen were initiators.

I am using Overhaul Dynamic UI, no gameplay changes.

Steps to reproduce the issue.
Spawn the Chosen one, set GA no scaling 2500 mid game date, 0.25 tech cost (for test)
Watch how they go throught tech

Expected result:
The Chosen can't research Wormholes tech until mid game date

I am lucky, i have a 2255 year save with womhole tech in progress. I added this file and screenshot too.

I believe the mechanism is that the Chosen won't research Wormholes in the early game unless they make contact with another empire; if that happens, they wake up early.

After a bit of digging, I think this is a similar loophole I've seen before with the Chosen - their events include Story8. That's an anomaly where a Derelict ship allows contact between two empires who have not already met. This accidentally woke up the Chosen early without anybody actually entering their cluster.

The one I got was funny - it was an anomaly where the Chosen were deemed the most delicious species in the galaxy and I got their contact info out of it. Great first impression.

In my game they discovered Dacha system guys... It's the only empire they met. Dacha even on other side of galaxy from wormhole...
You can see them on screenshot.
