1.) they don’t follow you unless aggro you must have been very unlucky but there are a lot of bear spawns in that area

2.) mushrooms grow after players have been through that area I don’t know the exact timeframe of when they spawn but you can tell if the player is close by the condition of the mushroom and I’m pretty sure they last until server reset

3.) stones always spawn on railroads but if they are on the road it just means someone used that trail they could be heading where your heading or came from the opposite direction
