Hello.
I stumbled upon a bug yesterday where I all of a sudden could not long rest. Clicking the long rest button did nothing and going to camp to click the bedroll did nothing.
After scrolling forums and reddt i stumbled upon a few others who had the same issue but it was has not been reported.
The bug can be reproduced if you attempt to click longrest at the same time as you enter combat.
I tried to go back the the enemies who triggered the bug to "clear" the combat tag but it did not work.
I tried save/quit.
I tried removing mods.
and a lot more.
The only fix was to reload a save before the bug happened.
So incase you stumble upon this bug, just reload to previous save. Hopefully the rollback isn't too bad
