I notice I can move vanilla crates. Will they respawn at the location they were orginally spawned at or the new /tls location?

Could I use this to move a green crate from Oxum's to Launch Site to balance loot crates?

No, only the entity itself gets moved.

However, when using Monument Addons, moving a crate spawned by a spawn point created by that plugin will move the spawn point itself. There have been a few requests for Monument Addons to support mutation and removal of vanilla entities and spawn points, so perhaps that feature could be supported in the future.

Thank you for quick response and an amazing plugin. Looking forward to what you will add in the future. Keep up the good work man!
