Give us a warning before we lose pages of items

I AM PISSED. I LOST IDK how many pages of RUNES AND OTHER INVENTORY after the stupid season ended. HOW DID YOU NOT THINK ABOUT GIVING US A WARNING IN GAME ON HOW TO PROTECT THE STASH? I HOPE ITEMS ARE RECOVERABLE.

They did give a warning that it will happen and how to avoid it. You need to cloear your shared stashes and they said about it.
