I’m on official an official server. I gave up last night after hours of trying all kinds of different things. One successful purchase came after relogging and drinking water (I was low) and another worked after I dropped some spoiled meat… After so many tries, clearly neither thing actually helped make it work.
At this point it’s gotta just be some kind of race condition or server side lock up… Basically try a lot of times and hope to get lucky. Or maybe they’ll patch it.
