I've had over a screenful of lye buckets just sitting in the ashery for ages now. I have plenty of room in my food stockpiles, and although barrels are tight, I've been able to make them fast enough to keep the rest of my barrel-using processes (brewing, etc) going fine, and can track down a few empty barrels if I search for them. The lye buckets just sit there, though...
And, of course, I can't make any potash because it won't find any lye.
I'm not sure why this is happening. I know that barrels are needed somewhere in the process, but if it's taking a year with all the barrels I have sitting around, I assume I've hit a bug.
It's fairly silly in any case, though; the bucket used in the potash-production sequence isn't even that important. The dwarves stupidly pour the lye into the bucket, then pour it right back out again to make bars of potash... and yet, if they can't find the bucket they just freeze up and complain.
There's a bucket built in to the ashery, though, isn't there? You need to use one to build it. Why not have them pour the lye in there? Other dwarves with barrels could come and pick it up if they're available, but that way you could also go straight from producing lye to producing potash without having to drag a precious barrel all the way over to your Ashery just so the dwarves can use it in the bizarre five-second ritual they use it for now.
