Subject: Fixed behavior of frozen bodies

Frozen bodies are now still ticked, but their velocities and positions are no longer changed. This change was made so that frozen bodies can still be ungrounded/unferried, and that passengers of frozen bodies can still be ticked.

Also fixes a compile error.
