That's correct, items I was clicking were not disapearring from the game world.
I'm going to see if I can replicate it for you and record a video, but there's every chance I won't be able to now!
EDIT: In trying to replicate, I'm unable to start the second level, when I click the start button, it jitters and nothing happens, I'm unsure if this is a known bug or not. I do have a video I can send to you on Discord if you like.
