A few days ago, I hired stablehand rosemary for two weeks. Yesterday, my pets were around 8/10 on hunger. Today, they are at 5/10. I have 39/50 (78%) of my stables filled and her pop up states that she'll take care of up to 80%(so 40/50 would be my limit).

I've been using her for a while and she always seamed to bump up the hunger level the day she is hired, and that didn't happen either.

This has been happening the last few times I've used her and it seams like more gold is disappearing the day after I hired her.

One clarification: the 80% refers to the discount. If you only have a few pets, she'll discount 10% of the price that it would cost you to feed manually. If you have a lot (I don't know where the increases are) she will discount up to 80% of the price per pet. So like instead of paying nearly 58k gold every day, when I have the stablehand hired I only pay about 11k per day.

On your stables page, one of the blue buttons in the top right is View Logs. That shows all of the stuff that happens with feeding. Maybe take a look there to see what's going on?

Ahh ok, never got that explained like that. Thanks for clearing that up!
