I'm pretty sure I downloaded the "hotfixed" version (not that there's any choice of other versions) but I'm still getting regular messages about sleep...

Definitely multiple messages, as if the game entered into an infinite loop...but at least they stop if I can move away... You see, it actually depends on where I am in the world--the huts (in the starting village) are the worst. They also appear to occur when around enemies such as those...bipedal dog/wolf-like ones or the deers... A bit annoying when you're trying to kill them...
