"GameManager" deleting gameComponets i add to it

This is my first actual "video game" so forgive me if any questions i ask in the future are really dumb.

Issue: My "GameManager" keeps deleting the components I add to it, I do not know why it is so, but I have spent several hours trying to figure out whats going on. Again forgive the the bad code, I am still learning. I am looking forwards to an answer but if you have resources available to send me to so I cant learn a better way of doing it, Id also appreciate it.

I put all my scripts in just in case I created some conflict between them

AGAIN I am still learning any help would be appreciated, including advice on cleaning up my code. My one lazy mistake is not commenting the code, which i can do if you need me too. Thank you to anyone who can help me <3 (self taught :/)

I dont know how the bumping works in this but anyone got an asnwer?

 

Don't think there is enough info here to say. What component are you adding that is being deleted? The only thing I'm seeing instantiated in the code are the bullets and effects, but neither appears to be attached to the gamemanager and I don't see any add components at all so not sure what you're doing.

 

I can not see anything getting removed in the code, the only issue you might have is the scenemanager reload you are doing, did you make sure you saved your scene before playing? Else it is gonna load the the scene where you saved last..

 

Thanks guys for the reply, i ended up scrapping everything and buil;d the game manager from scratch, but i appreciate the reply.
