These went live yesterday as of the last crash. I believe the issue with the crash has been fixed. It involved mobs activating zone alarms.
The [target] tag is now off by default and can be toggled using the TARGETTAG command.
The behavior where spells/skills will default to the target if a victim is not specified is now off by default and can be toggled using the TARGETSKILLS command.
The lost concentration message has been changed to include which spell/song failed:
You lost your concentration! You failed to <cast/play/sing> '<spell name>'.
The failed rescue message has been changed to include the person you failed to rescue. It looks like I failed to remove the old text, but the new text also shows up:
You fail to rescue <name>.
There were some additional internal changes that hopefully won't show up.
