Chunk Regeneration Problem

Hello Bukkit Community,
I have a weird problem while regenerating chunks, I am using the following code (ignore the "final" in front of the variables):

Code:

final World world = chunk.getWorld();
                    final int x = chunk.getX();
                    final int z = chunk.getZ();
                   
                    world.regenerateChunk(x, z);
                    world.refreshChunk(x, z);

Using this in a command does nothing at first, when reconnecting I see the regenerated chunk.
Although I am using refreshChunk() which should usually send the updated chunk to all players?
