Cave Bug Issue

There's a new bug issue that I found. When I was mining in a cave, I found a Wandering Trader and 2 Lamas spawned inside the cave. I have a Screenshot of 1 Lama but the wandering trader accidentally stepped the Lava and Died. And also there's same problem that When I'm in the middle of the raid, but I have to kill one more Pillager but he is missing and I Searched Everywhere like it took so long to find this Pillager & I Finally found him at the cave and I killed him, but I didn't get 'Hero of Town' Achievement & I lose the raid war.

 

Please fix this issue developers!!
