I recommend reinstalling because the quest will be very annoying otherwise, and if you have to set the variables to get through it, you'll miss Tweetybar's little comments, the ones she'll failing to say in the loopng bug.
I only downloaded Finch within the last 12 hours so I'm pretty sure I've got v1.2. I had the talking problem, I reloaded a Quick Save and she didn't do it again.
