Amount to rank up a fighter has doubled??

So within about an hour or 2 ago, the amount that's needed to rank up a fighter has doubled. For example earlier today I had a fighter that only needed 50,000 to rank it up, now it has changed to 100,000. The amount to rank up any fighter has now doubled🥺..  Is this a bug or a permanent change by the devs? 

     And also the amount of damage that's done by your opponent is way more significant.. Just a couple of punches from my opponent and it does way more damage to me than it did about 2 hours ago. If these kind of changes are permanent in the game I will definitely stop playing the game,which is sad because I actually liked the game and I spend money Into the game here and there. I buy the battle pass every season, but this is taking it to far E.A..  Mostly all my members in my guild chat said they will stop playing the game if these changes are permanent. Why make it more pay to play when it was already pay to play ,but at least it was manageable before these changes.. Now these changes are taking it to far.. I hope this is just a bug and not permanent changes to the game.
