Oh, that is a lot of objects! I guess I would just recommend that next time you delete as you go, sorry I couldn't help out. Hope you find a solution!
Yeah I know it's my fault, I am also stupid with the names.
"Spikes" is a main object in my game, I have like 50 different ones in my game that isn't being used because I was testing around as stated.
And they all have the name "Spike, spike1, spike2, sprite 32, sprite 66" ect...
For my next games I will always delete as I go and keep a good name scheme
