The thing is that what has been announced to be coming might be the contributor too. How? What if they already migrated some parts of the game to the new version despite that users are still playing on the current version? That can result to conflicts or negative effects.

From my side, what I have noticed to have changed since last 2 days of last season is that certain things (such as orders) did not work the same way; what was working before and how they were working has probably changed. Highlights have been also even more misleading. I feel (too) that more parts of the game got broken recently.
