Thanks for taking the time to play and explore all the content! I wasn't aware of any glitch with the treasure chests so you might have found a new bug 🐞Seems like you also found an issue with the casserole which is unfortunate. 🙃
I agree that a base area to cook at would be a nice touch, and it was something I wanted to include in the game. I honestly just couldn't figure out how in the time limit so I made it easier to cook anywhere in the dungeon. In the future I will definitely add cooking stations throughout the dungeon, with maybe an extra bonus for meals cooked at different cooking stations. Just a thought.
