Maybe there isn't enough memory to store them, so they are being purged? I will try to find a way to provoke this behaviour later, but as of right now, I have no clue when exactly this happens, nor what exactly is causing it - the only thing I know is that my projects at a certain point all adobt this behaviour - but when I let them render on a render farm it's fine.

Sometimes even just restarting Blender helps
