chest, any kind of chest like trip wired, ender, and double can't open when a slab (stone, acacia, spruce, deepslate, etc) is on top of it. This might affect players storage rooms who have compact designs in their bases so devs, would be kind if this was fixed before part 2 of caves and cliffs because probably a lot of players are gonna mine inside mountains and upon arriving to their compact storage rooms, they can't put away their minerals away
