A small mod to removed the restrictions on sleeping.
This addon 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 then you’re good to go!
Will probably need reinstalling following any future patches. I’ll check and update here as necessary.
