After interacting with an object's UI, that UI sometimes freezes, remaining open and visible in regular 3D view. Usually, the affected object will be a container, though I've seen it once with a greenhouse Field UI as well.
When this happens, saving & loading will "heal" the container's UI, but this seems to be occasionally associated with the object succumbing to "amnesia", apparently forgetting some interactions it had been involved in. Thus, items recently placed into the container may disappear from the game, while items recently taken out of the container may get duplicated by re-appearing in the container.
The UI-freezing bug is frequent with this version of the game, and I have now seen it causing "amnesia" twice in this version - once with the Rover's inventory, and once with a freezer's inventory.
In my mind, this makes it even worse than previous incarnations of the "inventory amnesia" bug, where "only" Inventory Boxes and ATV boxes seemed to be affected. Now no inventory seems to be safe, except the player's.
This "inventory amnesia" is a very frustrating bug (or family of bugs) that has been around for quite a while now, and each time it has me rage-/frustration-quit the game, hoping for it to be fixed in the next update; and it seems that all attempts at tackling this issue have been patchwork, rather than discovering and solving its root cause once and for all.
The game's current container inventory system seems to be fundamentally unstable, and no matter how much you reduce the number of scenarios that might topple it over the edge, there may always be one more scenario you haven't addressed, that may still send the whole thing crashing down and cause players to lose valuable items. It seems to me that you really need to replace the whole system with something more robust at its foundation.
