I have a server which I have been updating through the snapshots, but the world lighting in this snapshot gets corrupted.

I tried to copy the world in my saves folder and do the optimize world feature with cleaning the cache activated and copy it again into the server folder. But this only works for starting the server once, if I start it again it comes back to the previous status.

This only happens in the server version, if I run it several times in local  it doesn't happens.
