Ghost ship - NPCs and Locked crate not respawning

I have forever opened Deep Sea. After first time - patrol on ghost ship is not respawning & also locked crate not respawning as well.
Only regular crates respawn

"Respawn (Crates/NPCs/Hackables)": {
    "Enable Respawn System": true,
    "Check Interval Minutes": 30,
    "Min Distance From Players To Allow Respawn": 200.0,
    "Respawn Hackable Crates Via Ghostship": true,
    "Hackable Crates Count": 1,
    "Respawn RHIB Patrol Groups When None Remain": false
  }

Also note that after update loot respawns either in the air or inside the floor of the ghost ships. Not sure if this is related to your plugin or to RUST in general
