Windows 10: Weird Bug/Interaction on Cut throat Jungle False God Floor

On Instability 0 I was testing a team on my trickster spec, and when I defeated all of the enemies of the floor, it says the Portal spawns as usual, but I couldn’t find the said portal. So I tried to defeat the mini heads in Toruns realm, after defeating each one, it says the portal spawns, but I still cannot find it. So I summon creatures from the candle to see what happens, after defeating all of them it says Portal spawns but still cannot find it.
