A new glitch in Red Dead Redemption 2 Online (RDR 2 Online) allows you to make a lot of money. For this to work you must play with the duplication of animals and then sell them.
Here, we need to catch a panther or a 3 star cougar. In this guide, we are going to focus on cougars.
After you caught a three-star animal you need to take it to the stable in Valentine. You must reach the stable door slowly and as soon as you encounter the character right next to the door and the entrance animation is being triggered, you must press START, then go to "progress", now to "history missions" and then the first mission that appears you press the button to repeat it. You have to do these actions quickly as soon as you reach the height of the stable door and carry the animal on horseback.
Now you will see that the screen will remain black for a considerable time, but as soon as you see the icon of the weapon magazine in the lower right, you have to keep pressing X and forward with the left stick.
You must keep them pressed until you see that something strange is happening on the screen that is when the glitch will have been activated. You will end up appearing outside the stables and you will no longer have the animal on the horse's back. But don’t worry, turn back and enter to the stable.
Now you will magically reappear in one of the areas near the stable. Call your horse pressing up on the d-pad and you will see that a second horse approaches you with a cougar on its back.
Now go back to the stable, get off the new horse that has the animal on its back, and enter the stable on foot where the entrance animation will be activated. Here, the horse that you have left outside will disappear, dropping the animal that had its backs to the ground.
Now leave the stable on the back of the horse that still has the animal but you will see that the cougar that we had before on the horse is duplicated at the entrance of the stable. Now come back to do exactly the same, get off the horse, go back into the stable, the animation is triggered where the horse that will drop the animal that had its back will disappear, and repeat this process again and again to duplicate the times you want the dead animals.
In this way you can duplicate any animal that you carry on horseback in an infinite way and then sell them to earn lots of money.
