unregisterTile only gets called in the TerrainTile destructor after it's ref count has gone to zero. It'd be safe if unregisterTile was called prior to the TerrailTile object's ref count goes to zero. > Therefore it is still safe to investigate the raw pointers in the > _updateTerrainTileSet in Terrain::update. > > Do you agree on the assumption?
