Vadagar Bear disappearing after becoming invisible

[brittle heath]

I think the interaction with Vadagar Bear and the rune The Flitsmoke isn't working correctly. At the moment I used smite with daggers and became invisible, the Vadagar Bear did the cannonball movement and disappeared into the horizon in ball form, hilarious. I tried waiting and moving far away to see if he would reappear again, but he didn’t. The only solution was going back to a world three, abandoning the tale to cancel the votive. So far I’m 0/5 in attempts to kill the Vadagar Bear, he keeps despawning, or like in this case, the moment I became invisible he just disappeared.
