I have not had any Ep boost since Thursday in Fortnite. I'm level 37. My friend is level 26 or so and he still has it. Does that have something to do with the level, so that you only have it up to a certain level, and does any of you have the problem?
I have a solution for your problem:
Stop playing Fortnite
I just like to play in between & play with my friends, but I play as well as other games that may be a bit more popular.
