You can always do the both. If there was an "easy" fix that can be applied in a day or two, it should have been done.

Take all the time you think you can afford if yyou software is not released. But it is being used by customers and such a large bug is in it and if you are not reacting to it then imo it is a problem.

I think people disagreeing with me is unable to see from the perspective of customers. In this case a player that loses hours of progress because of a bug deserves some atention
