I have tested this multiple times, I was trying to 100% every item on a journey mode character and also found out about the autosave bug after my game crashed because of this. 
Speaking of which, I had to create a new world to get more biome chests. I had researched the keys, chests and corresponding items within them, and lost everything after the crash. Because the world itself was autosaving any changes made to it, those chests are now gone completely.
