Ah many thanks for the clarifying! That helps a lot 
Oh yeah I came from a C++ background back in the day, so I remember passing function parameters by reference (where changing that parameter actually changes the original value where it’s stored). It’s honestly been a while since I picked up coding and messed around with it. Right, normally passing a parameter makes a copy of the value of the variable being passed into the parameter variable, which is separate.
If you’re using fortnite native rounds system, everything in your map will reset correctly, no need to clean anything. Also in your case you don’t want it to cancel during the round since you’d need to keep that elimination handling script going, so I guess it’s fine to keep it
And ok gotcha! This is all really helpful to know, thank you so much!
