[HELP] Custom Dodorex Despawning after a certain time.

Hi Mezzow, Thanks for the reply. However sorry to be a pain but I dont quite understand. This is the order of what I did. Did I do anything wrong or miss a step out?

  1. I copied the dodorex into my mod folder with all the necessary files
  2. Removed all existing blueprints from the copy so the Disappear in time thing.
  3. Added it to the spawner and did the stuff with the dino entry
  4. Making it look custom.

what else do I have to do?
Hope that cleared up what I did. Sorry again, I am quite new to dinos and this has just thrown me.
