Why did the NPC fall?

I have watched this video several times. it's right at the beginning of the match as soon as my feet hit the ground . I eliminate the player, but I can't figure out why the NPC randomly drops.

No way you actually clipped that 💀

Yeah, I accidentally did. People can post what they want on their own channel. And the focus was why the NPC randomly died

I actually won the match with 17 eliminations. But sure. This was as soon as I touched down. The focus of the video was "why did the NPC randomly die"
