first of all, there's a problem with automating milking, as if you got more than 1 bot at the milking duty they try to milk the same cow, end up only one milking and both proceed, then the 1 with milk continues to put it in storage and the other is stuck trying to put a empty bucket in the milk storage. I tried fixing it, by puting down the bucket and picking up a new one that's empty, problem with that is the buckets is the same for the bots so it doesn't filter empty buckets from milk buckets.

another problem, when mining for metal you also gain stone, but stone has no usage, so I ended up with a tower of 1k+ stones in the corner of the map not used for anything

after some testing, I found out that, it is related to the problem with 1 bot starting a request reserving it from other bots, but when it finish the request the other bot thinks it isn't reserved anymore and tries to complete the job that no longer exists, it hasn't been much of a problem before automating milking.

temporary fix, make the bot milk twice in a row and if it already has milked it will just skip it.

I was about to correct you, when I noticed I am in fact not using stone to make metal sheets(?) anymore.  Actually, I believe this patch was supposed to make it a 50/50 chance of stone or metal, and I have been getting much more metal than I should be, which I suppose I shouldn't complain about, in retrospect.
