End question

[tawny wharf]

i'm customizing my end and when i go in the overworld and come back to the end some islans will always respawn did anyone knows why?

because the end doesn't regenerate every time you enter it. Once generated the dimension remains there

Eno, how exactly this work? I plan to add trees as structures in the end in my next project. I already done it by the past with a single structure(end shop) that was randomly generating in the end.
What exactly remains the same?
When I made some tests I noticed that into unloaded chunks changes were applied and once loaded, were staying the same

When you discover the map what you discovered was generated with the seed. This area of the world is therefore present and each of its blocks is contained in the map save file. According to what I read in the documentation your changes will be applied during normal world generation (generation which is unique relative to the seed). Your changes during generation should therefore be relative to the seed as well. So by unloading a chunk then regenerating it, this will always use the same seed for the same position and this chunk will therefore be generated identically (unless you have modified your custom generation in the meantime, in which case the new generation will be the same).
