That was one hell of a merge conflict. You may want to double check the height surgery portion to make sure nothing of yours got eaten.

All activeSlaves were replaced with getSlave(AS), so if that was it, everything is fine.

Apologies for merge conflict. If you switched like you described, should be fine.
