There is a message in Health card that describes the reason of an injury. "Cause:" sting there is not localizable, because it is hard-coded in the game. See RimWorld.HealthCardUtility.GetTooltip()

I was reported this twice, but ... still there.

You post contains more information than mine.
Too bad developers don't seem to read Bugs and Translation boards often.
We read them intensively during bugfix cycles, but it's important to focus on critical issues, and also to not risk breaking the game just before release. So we triage and you'll understand if this comes low in the priority list. You can read through the pages and pages of addressed issues if you want :)
Anyway, it's in the other thread so I'll lock this. Thanks.
