Describe the bug
In my game, after you die, the game map is queue_free-d and replaced with a new instance of said map. When first loading into the game, the detail layer is as expected. But after you die and the map is replaced with a new instance, huge chunks of the map's details are missing.

To Reproduce
Steps to reproduce the behavior:

1. Run a project that contains a scene with a HTerrain node that has detail layers.
2. Have this same scene be preloaded inside of a variable.
3. Queue_free the original scene, then add an instance of the variable-stored scene as a child of the root.
4. Detail layer will (in my case at least) be partially missing.

Expected behavior
I expected the detail layer to look the same whether or not the HTerrain node was part of an instanced scene, or part of the root scene that exists upon game boot.
