Log Damage setting doesn't function the way it says it does.
Instead, with ticked, zombies display as their name in the types file.
Unticked, all zombies display as "Infected"
Didn't investigate further because once again, it's another thing you'll just sweep under the rug, just like the 3500+ lines of memory chewing spam in the RPT files (that Nitrado tells us causes performance issues for the servers.)
