0.10.9 unable to complete realm quest

Hello,
I’m in Vertraag’s realm (Eternity’s End), quest told me to kill 2 invaders, I managed to kill one but I look all around in map, I check mini-map, I find no enemies to spawn anywhere. thus no invader to kill. I have to restart my game for that.

Thanks for your time and grats for 0.10.9 patch out as main branch! I truly love your game.
