I'm currently experimenting with hellblazers UI Notification https://steamcommunity.com/sharedfiles/filedetails/?id=1304210829 mod and trying to fix some problems. According to lua.log the following is nil: GameInfo.CivilizationLeaders["LEADER_JAYAVARMAN"] Why? Was sth about this changed? The code is: local leaderOne:string = PlayerConfigurations[PlayerID]:GetLeaderTypeName(); local civTypeO:string = GameInfo.CivilizationLeaders[leaderOne].CivilizationType; with leaderOne being LEADER_JAYAVARMAN and the second line results in "attempt to index a nil value". Printing GameInfo.CivilizationLeaders[leaderOne] shows that it is indeed nil.
