Elden Ring's Fringefolk Hero's Grave "Ulcerated Tree Spirit" boss missing from NpcParam.

Game: Elden Ring DSMapStudio: v1.10.0 Param: v1.10.0.1000

Essentially what the title says. Did a search for "tree spirit" in NpcParam and the boss in Fringefolk Hero's Grave is not in the list. Confirmed it by looking up each boss param's rune count with data on Fextralife, as well as double checking the region scaling applied to each boss.

Fortunately for the time being, the row will still exist - after all mapstudio is just reading game data. This will just be a case where the name isn't listed in the community-supplied names file. In general, you shouldn't take row names to be authoritative because of this. They are often very helpful for identifying things quickly, but may be missing in places or lacking details etc.

How do you recommend I ascertain which entry refers to which in-game boss / enemy?

You might have luck identifying them by any area scaling params, but more than likely you'd need to check the enemy in the map editor and follow it's reference to the param row - there's nothing stopping multiple of them using the same row, after all. Some rows you may find aren't used at all. I recommend the modding discord for further questions of this nature.
