well I posted before I read the thread by Victor, so while I understand them and all is ok, I still think that the devs could tell us a day in advance that something like this will happen... It will be the same when the official patch comes out. League races are planned and now as an organiser you are in a not good position when deciding "to race or not to race" because maybe there will be a new patch...
The days on which patches are released are in general not good for league racing... People get confused, when you say we drive the latest patch, some people may have problems upgrading/unlocking, not enough fast connection to download the patch in time, etc. and if you drive the older one, there are people who 2 hours ago installed the new patch out of curiosity and now don't have a way back...
I really don't see why we could not know that "sometime afternoon/evening there will be a new patch"... This is enough for everyone to adapt to it... It does not ruin the surprise (on the contrary, there will be 2 surprises, one with the news that sometime today the patch will come out and the second when it actually comes out...
