Alexsan, yeah, I have had to do that every once in awhile as well If things start seeming a little "fishy" or buggy, I'll save the game and re-load it. All of the problems usually go away.

** I saved and loaded the game and it's working again. (I'm using the Core Mod UI version)

*actually, there is no action icon at all. I can't even select do nothing/sleep for the worker

I have the problem, that workers, from begin of the game or also out of a sudden during the game, can't build anything. There is no icon showing (pasture, mine, plantation etc.

czarna_skrzynka - I actually just did that, I was thinking it may have been a download issue as well. Interesting thing is, I did get it to work after clearing cache and deleting mod files, re-installing them in order, etc. All my previous testing was done with Poland and every time I could not get the pastures to work. Tonight, after re-installing everything, I started a game with Mongolia and the problem is gone! I started another game with Poland and the problem came back, and I also noticed the workers had something like 12 grayed out build actions where Mongolia did not. I started another game with Rome and the problem is gone, and the build actions are two options after researching husbandry - pastures or roads. I hope this makes sense, I'm super tired, been troubleshooting this for quite a bit. Poland is my favorite Civ to play due to the free social policies, I hope they aren't bugged.

I had a problem with pastures before. I uninstalled the game and deleted all filles that were left (both in my documents and steam directories). Then, I installed game again, started new game with core mod, then added other and started a new game. Pastures work fine now.

Interesting note - no matter how many times I validate the Civ 5 game files, it always says 3 files failed to validate and will be re-acquired.

I also tried something different - set up a game with the core mod only, saved it, and then tried loading that save game with the sapiens mod added. It came up with an error an I suspected it would and crashed to desktop.

I've cleared cache, loaded mods in the specific order as mentioned in the instructions....I just tried it again and researched husbandry, no pasture option available.

After building Shandan Horse Farm, new horse resources does not appear. And there is still problem with city states, mentioned earlier. Besides that, everything seems to work just fine.

@MDMchan im guessing you didnt clear cache?

That or you loaded Core Mod and Sapiens instantly.

As a precaution with big mods like core mod, load it only by itself once for the first Cache. THEN load the others

@Ishtar-Sama - Well shoot, I don't know what to do then. I've started several games and research Husbandry right away and my workers can't build pastures on cows, sheep, horses....
The other bug I'm getting is one of my second largest cites isn't going past the 3 space worker placement after I researched the wheel. Then I found out the hard way that city states will not remain allies for more than one turn after I spent well over 1000 gold as a gift.....ah well, I'll mess with it a little more, I dunno.

@MDMchan it works for me? I have a Huge 12 player 24 city with full sapiens modlist.

The UI keeps bugging out but overall, the workers works perfectly fine. No crashes as well for some reason.

The only thing that doesn't work is city states

I started several games with different civs and different maps and am able to verify that the Sapiens mod is the mod causing the workers to not be able to build pastures. I did the cache clearing steps and loaded in the core mod first and then Sapiens each time.

I'm all the way into the Medieval Era and still can't build pastures, my workers don't have the option. Is there a trick that I'm not aware of to build pastures?

thanks for the tip on the city states. that worked.

For those who are unable to make City States allies for more than 1 turn, you can override GD_CITYSTATE_INFLUENCE_DECAY_EXPONENT from 1.6 to 0.001. This field is located within ...\Sid Meier's Civilization 5\MODS\__Gaia's Core Mod__ (v 600)\GAMEPLAY\GameInfos\CityStates.sql .
Save changes/ Disable the mod/ Remove cache ant d then start your saved game again

You will notice that the city state influence decay is too small (1.5 or 1.87)

@Gaia, to clarify, you mean it will work with this sapiens mod as long as the core mod version is used

unable to make City States allies (or friends) for more than 1 turn. what ever is either gifted or done with and envoy, the decrement amount per turn changes to match it. so the next turn you are no longer their ally. I am posting this on the core Gaia mod as well. This occurred after updating to ver 6.

EUI isn’t officially supported, but you can try this version: Gaia's Core Mod (No UI) .
I recommend using EUI v1.29i — it generally works better than the legacy version. Some tweaks may be needed.

EUI support?
