Gotten COMPLETELY softlocked in the wine cellar with the corruptive slime-drink. The hypno-tendrals swipe attack can launch you over to the side of the room with the drink and the core. Interacting with the core gives you a little scene. That scene SAVES your current location. You are now stuck on the other side of the room, with nothing to get you back from there, even if you're able to kite the tendrals to swipe you back to their location, the portal is stuck on that side of the room and you can't get back.
