The updates as of recently have been on about a 3 month schedule. Amount of content released per update aside, the game has not yet hit a threshold where it is "late" as of yet. They also did not release a date for the new update.
While releasing limited information is a bad practice, they have not yet done anything egregious, as some have suggested. The only thing they have done is make some patrons unsatisfied with the schedule of content creation.
IF they were doing this on kickstarter, where a product is promised at a certain time wtih certain features, people may be able to get a refund if they miss a date. However, they haven't even given a date to miss. In addition this is patreon. This is "pay to help us try to put a product out," not "pay for this product with these features on this date." People can pull money out as they wish. Im certain once the release happens people will either return or new people will show up to throw them their 5 dollars a month.
I just hope we get more content with Fluff Tooth in the kennels PATREON HAS REMOVED THE PREVIOUS COMMENT DUE TO A VIOLATION OF POLICY. MOVE ALONG CITIZEN. or with the minotaurs.
