question about launching modded savegames

[Silent Sorrow]

After I've used the modlauncher to play a game and saved it mid-way to continue later, do I need to launch it from the mod-launcher to continue play? The problem is, if I first launch the modlauncher and then click "load saved game" it just crashes.

But if I load the game from the standard SEIV game screen I don't think it's actually loading the mod since I don't see the (in this case) TDM-Modpack text at the top right.
