need a consensus, if the community will go back to 1.1 chain, we should probably do it, but it seems to me that 1.1 chain is not a good one, it is a forked one, not the original one.
The current chain the pools and everyone is on is the 1.1 chain (even though using 1.2client), that is why the 1.2 client is not able to download then chain by itself and why you need to run 1.1 first. The choice is pretty much go on 1.1 as we have been doing or go back ~6000 blocks to 1.2, if that is possible. Community will have to decide this for sure.
As john said and which seems to be the case by how the client works "It seems to me that someone forked the PHS chain and it is no longer the original chain."
edit* It's also possible 1.2 chain is correct and 1.1 is the wrong chain, will find out.
And I do know 100% for sure there are up to 6 other forks lol
edit2 and they are all at much lower height than the 'main' one
