Foliage Respawning
If you want foliage instances to respawn you can enable that in DT_InteractableFoliage under Respawning. You can set the minimum and maximum amount of seconds (it will choose a random number in between) after when a foliage instance should respawn. After this countdown is over the foliage instance spawns again at the same location but only if the spot is free. If it is blocked because a player is standing there or a building was created there it will reset the countdown for this instance and it will try again later.
All the respawning countdowns for each foliage instance that was destroyed is also part of Save & Load Game
