Earlier, I uploaded a video in regards to unusual behavior in the Senet game of the Tomb of Semerkhet. Trxye concluded that the Senet inconsistencies were caused by the game not resetting board variables once the game has already been played thus when you load a save before playing the game, it doesn't behave as intended.
With this knowledge and savegames while winning and losing the game, you can cause instant win and lose scenarios as shown.
Thank you Trxye for looking into this issue and discovering why this happens. :)
