Noticed that when in bathouse to laundry; items that are not currently worn are not washed. This goes both for items on horse inventory and Henry´s inventory.
Why should this be a bug???
It´ s the same mechanic when washing yourself in a barrel…
Only the borne clothing get´s cleaned…
Probably could agree with you, however, the mechanic Before patch 1.9 was that when using bathhouse, all items in Henry´s as well as horse inventory got cleaned.
Dirt level are already insane without mods. If you have to take 5 baths in a row to get all your kits cleaned, it is getting tedious.
