If you place a bet at a bookie for the favorite at 12 instead of 1.2 because the bookie made an obvious mistake, he is allowed to cancel the bet. This is a very normal practice.
In my opinion, this incident shed a very bad light on the kind of quality control which is in place here. It appears, as if the booster collation working correctly has not been tested like at all. Just test-cracking 30-40 boosters before deploying the new program version should have made this error very apparent.
And don´t bug me with that "it´s a Beta"-yadda yadda. If this game should ever go into production, there must be provisions made to avoid something like that (and the other one bazillion bugs you see with every new set). It would be a good move to install them while this game is in Beta to test, if these provisions actually work.
