Description

When using ray traced projector shadows, usually with multiple avatars under a projector light at the same time, the ray traced shadows can disappear without the text on the bottom left of the Advanced Graphics Settings window saying that they're being reduced for memory.

Reproduction steps

Go to Preferences (Ctrl+P) > Graphics > Advanced Settings...
Set Sun/moon shadows and/or Projector shadows to Ray traced
At least for me, it happens more consistently when aiming an object with a projector light into multiple avatars.
