Fyi, Sedan's don't appear to be leaving the little repsawn plants. Thought it was a one off, but had a blue, white, and red each not leave one. All others seem to be leaving the respawn plants without issue.
Also, I'm kind of surprised about all the people asking for birds nest and trash bag respawn mods... considering there's a chunk reset setting in vanilla now that literally respawns everything, even destroyed buildings when the player hasn't been around for X amount of time.
