Many objects drop and vanish after few second since Feb 6th

Many objects drop and vanish after few second since today
With or without filters, objects loot and vanish few seconds later and can not be picked up anymore randomly after few seconds.

When using a filter the hallow of light is still visible but the object can not be grabbed.
Without filter the label of the object is suddenly no more visible after few seconds.

Have you tried hitting the `z` key?

The behavior you describe is similar to what you typically see when you have loot hidden (by pressing the z key) -- when it drops it will show the text briefly, and then the text will disappear.

If you hit the z key, assuming you've accidentally set "don't show loot", it should show everything.
