Accidentally joined a glitched Goliath event

Hey, I got the game tonight and I was joining random online events when I encountered this glitch. I did not know what this event was so now my progress is ruined because I got boosted to lvl 100+ in an instant. Is there some way to revert back to my original level and money?
