A player that uses the https://github.com/DaEgi01/CitiesSkylines-CheckRoadAccessForGrowables mod complained that moving a spawnpoint with BSP mod does not trigger a revaluation of the road access and thus leads to a stuck road access needed icon.
Calling BuildingManager.instance.RoadCheckNeeded(ushort building); after the player changes a spawnpoint location allows the game to understand that something has happened that requires another RoadCheck. That should fix the issues.
Could you please add that to the mod?
