in only certain area, probably a chunck, all regular chest ender chest and shulker box disappear. The chest still occupy space but you can not see it and either interact with it (you can break it but not open, when braking particles are shown). Frames and barril are visible but items in frames are not and you can not interact with either of them. 

I really hope I don’t loose all resources inside! When I broke one of the regular invisible chests gave me back the chest but no of the items that where inside.
