The mission where you hunt a bear,I forgot my rifle on my horse,when I remembered I said,"Ok,I go back a few steps and pick up",since my horse was near the first footprint,near half the way,I got a mission failed,I literally only walked back by the same path I did before,walked back maybe 10 ~15 steps,I lost all progress after the first footprint.
Once, in the first mission that you buy a new horse, you must ride a black horse, but my game bugged, the horse did not appear, it was invisible, I did not know how to retray the game, what did I do?I walked ( with the cell ) far away opposite the place where the horse was, when I was in the middle of the camp (5~8 steps from the horse), I received mission failed message, then the horse reappeared, but curious, as in these two cases, I literally just walked a few steps contrary to the next point yellow.
What a joke,Rockstar lost their minds with this game.
