I lost my 400% battle experience booster when the game unexpectedly crashed and would like it back
Not likely to happen, I’m afraid.
I mean, you could submit a bug report here: Community Bug Reporting System
But I doubt it’ll do you any good.
Yeah it happen frequently to me when it was the halloween event period
I lost more than 1000% boost because I had to go to work after opening lots of chest middle of a night, you can tell how angry I got once I saw it all gone xD
