I can see Foundling Hospital in the pedia in-game, and I was able to successfully build it and have it work in a test game. I also discovered that if I set Foundling Hospital's <iMaxTeamInstances> to -1 in CIV4BuildingClassInfos.xml (so it's still a National Wonder, but not a Team Wonder), then no message appears and the National Wonders page works without any problems.
I'm working on it, it was a quick fix for displaying it in the main menu and it will be up with the next revision once I'm able to get Advanced Cargo Mod working (I've imported the code in the dll but it doesn't work as it's supposed to). But I've discovered that there are othe entries not being shown while in game: buildings like Plague Hospital, Planning Office and probably others are not shown while in-game. There could be a problem with civic-specific buildings, I'll have to look deeper.
