im experisencing the same problem, i got it on day 5, after i bought stamp auto sorter and its upgrade, ive played on browser, i can still rotate items just not move them anywhere. great game otherwise super fun:)
Ooh interesting, thanks! We had another bug report related to that exact upgrade, might be something tangential -- if it happens again, let us know if resetting the day through the rule book refreshing the page fixes anything.
