- after receiving a StartGame message, clients will wait until the game is loaded before reading new messages from the server
- the Item(prefab, position, submarine) constructor uses the position as the center of the item, not as top-left corner
- placing cargo items using syncedRand (items will be in the same position for all clients)
- less confusing waypoint/spawnpoint editing (spawnpoints can't be converted to waypoints or vice versa, and spawnpoint settings aren't shown for waypoints)
- more informative message about missing cargo spawnpoints
