prevent ship's ghost images

[MCLV-pandorabox]

If you jump the ship a further than 3 mapblocks, you see a ghost image of your ship due to the cache of the client. Once you get withing activation range of the ghost image, it disappears. To prevent this we force the mapblock of the source location to the players affected

Did you test this with ships split across multiple mapblocks? Also might be worth checking the distance traveled to avoid unnecessary sending.

[MCLV-pandorabox]

I did not test it with ships spanning multiple map blocks, nor did I bother checking the distance since this would add more complexity to a an otherwise super simple fix. that does not cause very much more data to be sent to the client.
I would suggest to just implement it now and perhaps, if needed add more complexity to it later, if so desired.

looks sane, thanks 👍
