Game mode: [Singleplayer]
Problem: [Crash | Bug]
Region: [USA]
As simply as I can put it, here is the problem I’ve ran into virtually every time I try to go and acquire Dagon Scales and work my way up to the final boss; No other area seems to cause this, except the Trident-wielding Mid-Boss temple specifically though some times I have had spats of resource hog/drop(?) or extreme lag when trying to work the final dungeon area’s levers and perma-trapping rooms with the prisoners and chests.
The lag doesn’t seem to hit as immediately as just going to fight the sub-boss, but going back into the water/stairs seems to kick it off. I also noticed it will multi-stack the effect of fresh air / dipping under water there, and once I kinda walked on water going to exit but the game physics went back to normal once the latency/resource/lag spike simmered down. However why I wanted to report this bug is that it will persist when leaving that area. Like to the point I went to fight one of the Children of Dagon (I think they are called) with the gas vents area, and the lag persisted quite horribly. I mean I don’t know if I ever hit a single enemy, ran around and tried to heal a couple of times, and it was just so atrociously frame-glitchy I was expecting the game to crash, though even when dying half by choice, half because the controller inputs would barely go through, it persisted even when re-spawning back on the shore.
It would persist for quite some time, returning to normal functionality briefly, usually when I had disengaged from any enemy for a time, and then slow right back down again. I mean I could count ‘Mississippi’s’ to the pace the frame-rate would seem to show and inputs seemed to register, or however you would best term that. If it’d help I could try recording on Xbox (It’s a One-S if this matters in analysis) when this happens for review. In the mean while I will just avoid that specific area like the digital plague, I don’t fancy fighting that sub-boss anyway because he’s very strong even without the resources-drop factor, but I have tried doing so for the sake of skinning him and trying to fight all the areas before going to the last one like a good adventurer should 
Either way I hope this helps, I do enjoy the game very much, but I have no idea why that stair case acts cursed and bugs the crap out of the game engine / game system. Thanks once more and good luck, cursing at the TV may help alleviate high blood pressure?
Steps on how to reproduce issue:
- Go to Sunken City, specifically the Trident-Wielding Sub-Boss Room
- Combat Mid-Boss, Use Stairs to attempt healing
- Even if you die, major resource / lag issues persist.
- Repeat if sadistic
