I just uploaded a new build to address some of the saving bugs people reported. Let me know if you still have issues (click the report bug link for the fastest response).
RentToKill.. That was an error with the dialog. They won't recloak if they kill their target. I have updated the dialog to correct that.
Everyone else: I made Level 4 a little easier. :)
SeanB2008, please file a bug report when/if it happens again *immediately* with the time and the name of your opponent so we can find and fix the issue.
