Comment:

looks like a Common::File calls CCArchive::createReadStreamForMember("049.att."), which calls BaseCCArchive::getHeaderEntry which tries to convert file name to resource id.

In case of file name "049.att." it is converted to existing resource with id=55679 and file size 5526.

The dot "." was added in Common:: File::Open 

	if ((stream = archive.createReadStreamForMember(filename))) {
		debug(8, "Opening hashed: %s", filename.toString().c_str());
	} else if ((stream = archive.createReadStreamForMember(filename.append(".")))) {
		// WORKAROUND: Bug #2548: "SIMON1: Game Detection fails"
		// sometimes instead of "GAMEPC" we get "GAMEPC." (note trailing dot)
		debug(8, "Opening hashed: %s.", filename.toString().c_str());
	}

I guess that resource loading by ID is a MM1 thing, so my best workaround now is: 

void SpriteResource::load(const Common::String &filename) {
	_filename = filename;
	Common::File f;

	if (g_engine->getGameID() == GType_MightAndMagic1 && f.open(filename)) {
		load(f);
	} else {
		File f2(filename);
		load(f2);
	}
}

    7 I have a dirty workaround: https://github.com/scummvm/scummvm/compare/master...yarolig:scummvm:carnage-hand-workaround
     7I had a dirty workaround:
