I am playing the Nathaniel Hawkin storyline, the governor of Jamaica asked me to sneak into french occupied town of speightem in Barbados.
I landed at the far beach. So it is 01:10 am in-game, i am hiding in the tall grass by a low hill ( i would not call it hiding) and facing the two guards standing by the gate outside of town. I successfully knocked out one guard with a cobblestone without alerting the second and then realized i have no stones left. I was like: Damn! this is cool. So, i loaded (not fast travel) a save game from where i was in the ship before landing on the far beach, i took 17 cobblestones from the ship chest and tried doing the same thing i did to the guards, only this time when i knockout one guard the other guard attack me. The weird thing is that if i load the savegame from the ship before landing and i take only one cobblestone then i can knockout one guard and the other will not be alerted. I tested these scenarios again and again and it seems like the game does not want me to use enjoy a little stealth.
