How well does the AI cope with having this ability? Does it even work for them?

very fun leader. Building your own frankenstein civ is amazing :D

I'm happy to provide additional information around this error.
Problem #1 - User didn't look up at the top right corner of the screen.
Problem #2 - User did not click on the thing

:-D

Checked again, the mod works perfectly. Can't wait to give this a real run-through. Super interesting mechanic (as with your other leader mods). Sorry for the false alarm!

Just to be sure, ability activates in top panel (top-right of the screen) and it should be changed from "Sun King (0)" to "Sun King (1)" and after you left-click it, you can choose an ability.

What is more, it activates on GAME era change (related to golden/dark age), not your personal era based on civic/tech tree.

So now, which issue it is:
1) No button visible.
2) Button stays at "Sun King (0)"
3) Button says "Sun King (1)", but left-clicking not working.

Thanks for reporting.

I'm not getting the UA to activate for me. Only tested up to the 1st Era change. Fully up to date and all DLC here.

This sounds pretty fun, ngl.
