National Park

I was using the Maximum Wonders Mod, but all that does it put all the wonders on the map with a huge map. All the wonders were on the Map and only FoY and Lake V had issue. Both cities were off by themselves so there wasn't an doubt which city it belonged to, but I have had cities that had a single wonder within 3 tiles and was able to build the National Park in both cities off the same natural wonder. I too looked at the code and it is pretty straight forward. I think Firaxs did something. Don't worry about it. I was having some conflicts with a few mods that I play with but this one wasn't one of them. I may combine a bunch of the mods together to eliminate the problem.

4.) Is it possible to post your save file somewhere that I could download it and use it for troubleshooting? I'm not sure if Steam allows you to put attachments in a PM. You could also try sending an email through my blog: http://www.megabearsfan.net/contact.aspx . I don't think anyone's ever tried sending me an email with an attachment via the blog, so I'm not 100% sure it will work :/ You can try it out and let me know here when the email is sent, and I'll see if I received it. Put "Civ V mod" in the subject or something like that, so I don't accidentally delete or spam it.

In the meantime, here's a few troubleshooting questions:
1.) Are you using any other mods? Specifically, anything that might affect natural wonders? I know that mods to disable Fountain of Youth and El Dorado were pretty popular. Don't know why this would affect Lake Victoria though...

2.) Are you sure that you're building the National Park in the city that actually owns the wonder tile? Civ V is a bit confusing about how tile-ownership works. Only 1 city technically owns a given tile, even if multiple cities' workable radii overlap that one tile. Only the first city to claim that tile actually owns it. So if another city had annexed the wonder tile, then the National Park can only be built in that city, even if you swap which city is working the tile. I hope that makes sense.

3.) Do you happen to know if Lake Victoria and Fountain of Youth are the only wonders affected? Or are they just the only ones that you've seen so far?

I tried looking through the code last night, but apparently I don't have the most up-to-date source code on my current machine. I'm going to have to check through my old hard drives and see if I can find the code, or get the code from Steam. That being said, the Lua script is pretty straight-forward. It simply checks each tile owned by the city. If any tile contains a plot flagged as a NaturalWonder, it allows the building to be built. So unless Firaxis removed NaturalWonder status from those wonders, or you have a mod that changes natural wonders, I'm a bit stumped. I'll look it over once I get the up-to-date code.

PC of course. I thought Macs were just for listening to music. :)

@Small but Slow:
Thanks! I'll try to take a look at it sometime this week if I get a chance. If I release an update, I'll be sure to post on here to let you know.
In the meantime, sorry that it's not working.

Just to be clear, are you playing on PC or on Mac? I don't own a Mac, so if the issue is only on that platform, then I probably won't be able to troubleshoot it.

It's the latest version. Only reason I really noticed is we were playing hotseat with the Maximum Wonders Mod so all wonders were on the map. I had a little trouble with all the mods working, but I assigned load orders to them and it fixed most issues. Still love your mod. I just found it about 6 months ago and started using it. Thanks.

@Small but Slow.
I had updated this mod previously to support the expansion wonders. Are you sure you have the most recent version of the mod? I can try taking a look later this week, and see if something broke.

Don't know if you are still updating this. Great little mod. On the last game update the mod won't recognize Lake Victoria or the Fountain of Youth as Natural Wonders so it doesn't give the option to build a National Park.

I think you can create a new building for Isabela (like those UB from other civs that replaces X building for Y) it use the same description, text,etc, but its a new IDBuilding:

ID_Natinal_Park National Park, description, gives...
ID_Isabela_Nat_Park National Park, description, gives...

In the end the player will think it's the same building but Isabela will get the extra Yields
