In the assign colonist screen, the colonists vanished from one of my huts. I haven't been able to reproduce it unfortunately. I'd send you a save file, but I don't know where they are. Edit: It is possible to move additional colonists into the hut. They will all get the rest benefit.
I've got a corrupted save file. Most of the assets on the island have vanished, and I can't interact with the screen besides entering the main menu. This issue can be reproduced very reliably by clicking the "save" button multiple times.
Edit: Version 0.8.1, Win 10 64 bit
