Ashen Cavern and Lost Invasion Issue

[coldreactive]

After going to the right side of the Ashen Cavern from the entrance of the more man-made section, the player can trigger a Lost Invasion. However, it's possible to glitch this out where the invasion never ends. (IE: No more enemies spawn, but the invasion doesn't end.)

The exact conditions I had were... earlier in the area, I had Louis push an enemy off the map, and he'd stay there guarding forever. That was clear across the map near where you did the cut-scene with a certain NPC when you came in. So he stayed there, and I just pressed on without him teleporting to me. Eventually, Louis saw fit to teleport to me during the invasion after I killed three enemies. After no more enemies spawned, the Invasion didn't end, and the battle music is stuck being on.
