Life Imitating Art is still bugged. The final part where it says to go to the abandoned house, you check the pages and then fight a filthy secret worlder. When you check the pages, the filthy secret worlder won’t spawn for a bit. 30 seconds or a minute. I haven’t timed it, but when you’re just standing around waiting it’s forever either way.
Here’s what’s happening. When you get to the step telling you to go to the abandoned house, when you first approach it the filth line on the ground comes out of the barrel towards you. This should spawn the filthy secret worlder, but since you haven’t examined the pages yet it doesn’t. This puts some kind of cooldown on the spawning.
What should happen in stead is that when you approach the filth doesn’t emerge from the barrel. That should only happen after you check the pages on the ground. This should spawn the filthy secret worlder immediately without waiting.
