Regarding large ships

[Triu]

When building large ships, over 7000+ blocks, sometimes deleting blocks causes the block to be removed, but the part still shows until something is put in it's place or player leaves the game and re-enters (single player.) Happened repeatedly to me, not sure if this would happen on small crafts with many parts. Currently my ship has 7886 blocks, 0.29 billion m^3 volume and 6.5Mt mass, it happened before this point, around 7000 I believe I started noticing it. I would also like to note that deleting blocks in a group of around 50+ causes a lot of processing power to be used, and deleting thousands can freeze up the game for 10minutes+ perhaps this can be prioritized for large projects? Not sure of the teams priority for those wanting to build planet size craft etc.

 

*Edit this just happened to me again under 500 blocks.
