Lost a Formation experience, just a bug or?

same here , all formations were reseted. I think was a general reset for all teams.

just noticed, played a friendly, my opponent had a normal formation experience...

I think every time the season changes it will be reset

Plus there is an update rolling, where the formations exp will be implemented. 

To my knowledge that exp was just visual, but seen on discord @nicmo saying is getting rolled now between seasons. 

every season starts and the formation experience is reset, this kinda simulates real life and gives the opportunity to everyone to switch formations.

formation xp only accumulates on official matches.

i will be posting the formation xp update probably today

ok, thanks for answer
