save game crashes

[Druthlen]

So I load the game and it loads fine. I click on the construction icon for the list of builders and it comes up with a error. continue and the game continues but cant access the builders list. if I click quit it quits. This happens ever time I try to access the builders list. Very upseting that my game is ruined.
