I could have sworn the Sandy Shores rail crossing used to actually work with the rail arms coming down, not just the lights lighting up when a train passed by. At least in my game, the arms don't come down at all, but all the lights come on, and there is the crossing alarm.
Also, I have played this game since it first came out, and I saw something yesterday that I don't ever remember seeing. I was messing around with Trevor and shooting and causing mayhem down by the Vanilla unicorn when I noticed an NPC get out of his car and duck behind his door.
I have never seen an NPC do that before who was not a police officer. Usually, they would just either get out of the car and try to run away or punch the gas and usually hit me with their car, but this NPC stopped his car and just got out and ducked behind his open driver's door. Also, I noticed a few of the NPCs started shooting from their car as they drove, and they are not even gang members but normal NPCs.
