When trying to edit a custom islands, the LOCK no longer works, so it’s always starting from scratch.
For example when editing my custom islands, I will lock the cliffs I added because I don’t want them changed. I click apply to add or change any other rocks yet EVERY single thing in rocks changes, including locked items that I wanted to keep.
There is also a similar issues keeping the SHAPE of the island as well.
Trying to change the terrain height but keep the island shape as it was exactly what I wanted. Clearing the change shape check and trying to lower the terrain height also changes the shape of the island in error.
These functions seem to work fine as long as it’s the initial creation of the island. Attempting to edit these islands later you cannot use the same shape nor can you lock trees, rocks, etc. that you have previously added as they will always disappear regardless of being locked.
This happens regardless of seeded world.
