I'm also encountering this issue. I'm playing with my wife & son and none of us have had a base raid since the winter update. To make it worse, the game won't let my wife & son sleep to advance to the next day. We set our spawn point at our beds within the base, and I'm able to sleep, but they receive the message that they cannot sleep with enemies incoming. They have to quit the game in order for me to sleep and get sunlight again. Very infuriating!
