I was just playing hollow knight on switch and was getting the nightmare grimm. I got the one in the fungal core at the same time he killed me. The last bench i was at was the fragile charm one. For whatever reason it counted twice when i respawned there so i didnt have to get the Hive one. Im sure yall know about this? I was just wondering though just in case.

Huh interesting. That could be really useful for 106% and/or 112% if anyone figures out how to use it consistently.

Very interesting, but I don't think it would be useful for 106% (assuming if it only works for the Nightmare Grimmkins), as 2 of the 3 you get are directly tied to the route (Brumm and Hive Grimmkin), and it definitely wouldn't be optimal to die to the Grimmkin in the Hive to skip the one on the way to Ancient Basin. Neither in 112%, because you don't get the Nightmare Grimmkins, but only abandon the Grimm Troupe.
