Bug Description

Raised by bots in #3463

GameStateMap::xfer() sets the flag before map extraction and save-data transfer, but clears it only after TheGameLogic->startNewGame( TRUE ) returns. If the transfer fails, GameState::loadGame() calls TheGameEngine->reset(), but GameLogic::reset() does not clear m_loadingSave. The failed load can leave the game logic marked as loading a save.
