I have recently installed the game on my Mac and have gotten access to the White Jester, Blanch, for the redeem codes feature. Whenever I walk in front of him and click e, the item query window pops up and the game stops responding (i.e. I can not move in the game nor can I write in).
I am playing on a Mac (as mentioned) on version 1.02.
It would be slightly annoying to lose access to the EARLYACCESS code over this.
