Obedience Keeps Dropping

Daily the obedience drops by 1 unless I feed at 150%. This didn't used to happen.

Didn't have this problem for the first in game year, but now can't make it go away.

I have a slavedriver, cages, and intimidate 4 on the slavedriver. I sit between 26 and 29 slaves and always keep my fighter numbers up. There are no negatives on enduring effects... any idea what's up and how I fix it so that I don't have to 150% food every day to avoid a unrest.

Edit: I always rest with "post extra guards."

Aside: Is there a better place to post and discuss things like this? Couldn't find a Discord for the game.
