I dropped by mistake the shovel on this barricaded roof accidentally, but it did dive through it like a ghost, I couldn't find it somewhere in the basement or the first and second floor and I am assuming it left our world, and without it, I can't progress further. Now I am obliged to repeat from the beginning.
The second bug is with the lady, when she catches me while the ice-cubed key is set on the furnace, she wants to take it back, and boom! She's stuck there, can't take it bc it's too hot and I can do anything without being worried.
The third one is with the police officer: when I go to the second floor and drop something to make a noise between that bed and the toy car that is associated with the blue key, he just goes there and jumps to investigate and there we have another stuck keeper
