Patch 1.04 is apparently responsible for making all the NPCs standing around the module injured. It has something to do with current hit points versus max hit points. Here's a thread talking about it:

Reports suggest that this only affects previously created module. New modules don't seem to suffer from this bug.

A suggested fix was to manually look at the characters' current and max hit points in the Toolset.
