Enemies sometimes get deleted

Help and Feedback Scripting Support
#1
  1. What do you want to achieve? Keep it simple and clear!
    Basically i have this enemy that attacks other npcs
  2. What is the issue? Include screenshots / videos if possible!
    When the enemy kills an npc, it gets deleted for no reason, i have checked the code but so far nothing seems to be deleting it
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    i have tried rescripting and cleaning the code more, but still the same results.

Any help is appreciated

It’s hard to solve this problem without context. Can you send the code?

Nevermind. i had a setting called StreamingEnabled, sorry for the inconvenience
