Oh man, that makes so much more sense - thank you for the guidance on tuns. I wondered why I was noticing some fluids being stacked “on top” of them instead of “inside.” I’ve tried to avoid having barrels for each drink, because I feel like if you produce at least a bit of all of them it would take a lot of space, but I suppose that lends some credence to building two breweries.
On the note of the smaller supply casks, I have four of them set on a small bar counter, but they never get filled - the casks themselves can be picked up by the Hearthlings, but for some reason they never stock them. I haven’t watched yet to see if they’ll be filled when all other restocking tasks have been completed, so I don’t know the cause - I had this problem on the aforementioned last save, and what finally fixed it was undeploying and moving around the bars and the casks. In the end, it was all exactly the way I had it before, but maybe moved over one space.
I sort of figured that it was just late-game performance for the restocking issues, but it seemed to be a little inefficient even at the beginning of the game. It’s not terribly game-breaking, but if I want everything to end up put away, it takes about a day or two in-game for them to finally be finished.
