I have encountered some problems with hedges a while back but they haven't been reported here yet. Planting versus tiles next to the tile border I tried planting a hedge on the border with on one side enchanted grass, the other cobble stone. Planting a hedge is not possible. I tried planting a hedge on the border with on one side a farm tile, the other cobble stone. Planting a hedge is not possible. I tried planting a hedge on the border with on one side a dirt tile, the other cobble stone. Planting a hedge is possible. Dirt/dirt, grass/grass, dirt/grass and those in combination with pavement works. Other tiles need to be fixed Bisons walking through hedges I use 1x2 pens for animals with 1 iron fence and the rest hedges. Put in bisons I wanted to keep there. I come back the other day, and the run across my deed. All had left the pen. Hedges don't seem to block movement of bisons.
