When I open the ruin hole and jump down there, I raid every single thule in them. After exiting and being away from it for some time then entering ruins again the nightmare cycle bugs out and the nightmare lights and cracks start working early, but not all of them, they are active or inactive random while phase is off. The phase fixes the problem
Steps to Reproduce
Removed the ruin plug, entered it, raided everything, exited, was away from ruins in RoG world till I needed something, went back down there and then the stuff happened
