I mined a bit on the exoplanet Jaroth.
It definitely has a small delay before the new block appears.
It is a bit more prominent on Sand and Gravel blocks. They sometimes appears 1 second late and they do sometimes reappear after i destroy them. i don’t if these type of block are heavier on the data side than the basic rocks and we don’t get that info quickly enough from the chunkAPI.
