did a quick search in my game files to see if there are any compatibility issues with CQUI (and any other mod I have loaded) and there are none.
This is a replacement script for the EraCompletePopup.lua, so any changes to that file by other mods or by game updates will cause problems.
For the current version, everything looks okay except for what I assume is a mistake in line 17 of EraCompletePopup_XP1. I'm too noob to guess at what problems this might cause, however.

This mod is a lifesaver!

You must have Rise and Fall for this to work. Doesn't work with Gathering Storm for whatever reason...

Vicc. Yes it does for me on PC with Windows 10.

Does this work with Gathering storm?

Can you make it work with Gathering Storm expansion only? I need Rise of Fall atm

Thank you so much for this. Dark age gets really depressing.

Yes. At least on my computer :-)

This mod is working with september update?

Re: Sept Patch. Mod seems to be working okay.

Much appreciated!

Gee.. i had given up of ever seeing this update. Glad you could find time to do it. TY!

Excellent. Thanks abstr.

Updated. Sorry for long waiting...

Yeah it's been dead since the April patch. My old eyes need this. Sad to see it go.

Oh, I was going to use this, I didn't realize it wasn't working.

UPDATE PLEASE

UPDATE PLEASE MY EYES ARE BLOOOODING

It does not work currently.

This mod didn't work in my first test game after April patch.

With newly created games, works with golden age, but not with dark age :-(

Some mods make you hope that Firaxis will never upgrade this game.

Both my squinting eyes are thanking you sharply -- once again! :)

Does it work with saved games ? Because at the moment it did not in my current game :-(

Wow ! Thank you very much ! It was a pity those F*$é& changes of bightness !

Updated

Please update for GS !

Please update fot GS !

Hey, is it possible to make a mod, where the brightness constantly is like in the dark ages? I really like the darker look :)

What I mean is that I wonder if this mode is usefull now. It looks it's no needed anymore.

the code ist different in GS

Yes, can you update this mod for GS ?
It will be the best

I kind of wish this mod was updated for GS...

Great Job. Please update this mod for gathering storm. Thx!!!

This mod was a gift from the heavens. Please update to work with Gathering Storm

@mprata : Have you tried deleting the Cache Folder and the Mods.sqlite File, found in My games/Civilization VI. Sometimes there are bits and pieces left in these 2 from previous versions that cause weird things to happen to Mods.

I notice that it is random, must be some Mod indeed. Sometimes it works, sometimes dont. I think it can be resourceful 2, but am not sure

@Mprata : I'm not sure how to help you. I have no problems loading save games with this Mod. It works perfectly. Are you using any other mods. If so, one of them may be clashing with this mod.

@savoir10 i start a new game and its works fine, but when i reload the game it crashes. It was working fine at the start of the expansion, not any more. I found that if u dont quit the game it work perfectly.

@Mprata : I think this mod will only work with new games. It will work on these new games when they have been saved and reloaded later. However they will not work on old games that were saved before you loaded the mod.

It's not working, if u reload it broke.

This is just what I wanted.. up until now I have actually not wanted the golden ages because it gets so horribly over saturated.

Tested: Not broken

Hi ! It looks like spring patch has broken your mod :-(

you should make another version of this that sets the default to the dark age brightness and doesn't change

Great mod. I find the game partically unplayable when in a dark age and my screen brightness drops so much that I start getting eye strain.

Thank you!!! I've been getting eye strain from dark ages dark colour range.

Great.. Thanks! :)

thanks man!!!

hhhhhh
