It seems there are 2 chains. There are still many that haven't updated. The coin is taking the longer chain.
All please update to v1.3.3/v2.4.
The main pool is on the latest version.
We will wait for some time till most update otherwise we need to revert back to the old version.
The p2pool I'm on is on correct version too, and gives a warning that some nodes need to upgrade.
Haven't had a share in a few hours from it.
I didn't think we had that many users that have not paid attention.
