Hmmm, interesting... It looks like a common thing has cropped up in theory. The ones working correctly for hirelings are Halflings or Dwarves thus far. Checking for other identical races on the hireling list to see if they are also working properly, brb.

And confirmed. Barbarians Dwarf and Human, the Dwarf had no ptoblems being affected by Death Salve as normal and as expected. The Human one however had trouble. Tried with the FvS Halfling and was also fine. So it is almost 100% certain it's a "race" issue here at the moment.
Currently checking which of the other races fail. Currently confirmed Humans are problematic. Checking Drow, Warforged, and any other available race. Unsure what the Onyx Panther is supposed to be but they're fine.

(Sun) Elf, Drow (Elf), Warforged, Human are all confirmed impacted by Death Salve not working properly on them.
Halfing and Drwarf are confirmed fine.

Teal is not working with this.
Feywild Satyr Muse works fine, as is the Panther (and likely Lion as well as they're the same).
Suspect that the ones that are naturally "shorter" are all OK. Anyone else that mght be based off of the medium or larger races would be not working. Still need to run through them all to test, not had time tonight. Will check another time if someone else hasn't done it by then.

And confirmed that Frogo and Darling are both fine, suspect because they're shorties in code. Just look different.
