Our brewer made a couple of drinks Screenshot - e199ee59440dc92a9f776927ae3d0811 - Gyazo and Screenshot - fcbfbab01d5fd1d72520ed95396cc111 - Gyazo no one can pick them up. well I can reset them but i lost all the work and the booze 
it is likely that some update lost the maker data for the drink. there is a long spoil timer on fermenters and eventually the wait for maker timer will run out before the spoil timer. at which point the maker or the fermenter owner can get the drinks. failing that Drakkhis can usually make it right.
I do however advise running the latest update you can find right after collecting the drinks.
