That's really weird, no idea how this can happen.

Could you please try to play with the same set of files loaded using the latest devbuild ?
Saved games are not compatible with 2.4.0 although I have nothing else to suggest at the moment.

Where does it crash?

Code: Select all

void FSavegameManager::DoSave(int Selected, const char *savegamestring)
{
	if (Selected != 0)
	{
		auto node = SaveGames[Selected];
		G_SaveGame(node->Filename.GetChars(), savegamestring);		// <-- here
	}
// ...

The value of node is some random bunch of bytes, the value Selected cannot be determined because of optimization. Probably it's out-of-bounds read caused by an invalid value passed from scripting code.
