I can confirm this issue too, for me it actually caused all my player files to not save, so for some reason all player files where gone. It wasn't a huge deal since i have frequent backups, but seriously, this isn't a snapshot, this is a final release... this needs to be fixed ASAP.

I believe that in SethBlings Snapshot-Video you where able to see that the Skeleton do fight back, you might just have gotten unlucky.
It is a bug that all Playerfiles get cleared in the Update, that means your Fakeplayers probably just got deleted.
