A friend and I were playing and got 300 wood to build the bridge at the beach, but once my friend built the bridge it did not build it for me so I couldn't cross.
I've only seen that while watching a twitch stream, but seems once the bridge is rebuilt other players need to leave, then come back to the beach. When the player rebuilds the bridge their screen blacks out and the full beach map loads. Everyone else needs to leave and come back to force the reload. Sent from my SM-S727VL using Tapatalk
