Version 1.1 added two new states of sedation (woozy and residual). In these two states, the pawn can walk around, but has significantly reduced stats.
These reduced stats can cause a lot of trouble like: hunters can't outrun angered prey, builders routinely fail construction jobs, buchering wastes loads of resources, and probably many more.
Unfortunately, there's no way to order a partially sedated pawn to go to bed and not cause trouble, because the game doesn't currently recognize the pawn as sick or injured.
Please allow us to order partially sedated pawns to 'Rest until healed'.
