About 50% of the time when I try to start the game it crashes (without an error message) when I hit "Start Game" on the launcher. Recently I've been playing with several mods installed (I can provide a list if necessary), and I have a feeling that that may have something to do with it, but I think that the problem may lay in the mod loader itself rather than in the mods as the crash occurs long before the game would be expected to have to call any broken rooms, monsters, classes, artwork, etc.
