Bug I've not encountered before, even on my first short run through of Alpha 20 - basically some containers that would usually contain loot don't show the usual "(E) to open" prompt. I've tried putting the bedroll down, picking it up, logging out, restarting my computer, verifying game files, but nothing seems to fix it.
Playing singleplayer on PC Windows 10, with server options set to friends only.

It's not all containers, in fact it's only a small amount that I've encountered, but it has happened on main stash, medical supplies, crates, toolboxes, one trader's broken workbench, chem station, cement mixer, and some store shelves so far.
