I’ve removed the restrictions on sleeping. This changes only a few lines of code in one file so it should be compatible with a lot of mods. Check to see if you have the following file already:

S.T.A.L.K.E.R. - Lost Alpha\gamedata\scripts\la_actor_sleep.script

If you DON’T the you’re good to go!

Will probably need reinstalling following any future patches. I’ll check and update here as necessary.
