I began having this problem yesterday while running 1.5.2. The game runs normally up until the point where I select a saved game to play. When I click load, it processes for a few seconds and then goes back to the way it was before; the "load" button becomes completely unresponsive. I've been using the same mods for quite some time, but the game only started acting up recently. I tried deleting my save files except one and running the game offline, but it still hasn't worked. Has anyone found any new solutions?
