Server Rollback is BACK again now in POE 1

Pretty much don't know about other region, but happened alot in Asia server - Jp and Sg server and never fixed at all.

I never had a server rollback once in POE 1 since Settlers of Kaulgur,
but since POE 2 0.2 , i notice there was a constant problem with a game rollback.
Actually started as a problem in 0.2 league start, now this problem happening all over POE.

I don't know how GGG team may resolve this problem that is more annoying then just game crash, because it just not only make you lost progress, but your map (mostly) just gone. imagine if you in middle of fighting uber boss using all those hard farmed fragment.

Here just hope without any expectation on how they fix it, because the root of problem may came from lot different things.

Cheers.
