Help required when downranking level!

Hey there,

Over 800 gameplay hours ago I ruined my savefile by turning it into level 75.

Now I've been trying to get my regular level (Should be around 68 ish) back for ages, but it doesn't work.

I've had people tell me to set my scores down to -999999999 but doing so results in Rocket League still keeping my Rocketeer rank, and my cheat engine turns the numbers around really strange, let me show you what I mean with a screenshot.



Whatever low number I put into the Cheat Engine, it always goes back up to like 430 million, I'm completely lost on what to do.

Also the level alter things when the internet is off works too, but once I restart my game after the internet is back my level turns back to 75.


Any help would be greatly appreciated!
