I recently redeemed my code for the Pathfinder 2nd edition physical book from the most recent Humble Bundle offer. The code appears to be successfully redeemed, but I do not see any pending option for shipping it to myself.
Let me know if there is any information I can provide to help fix this.
It looks like Calliope was able to take care of your pending Humble Bundle Order but please let me know if there is anything else I can assist you with!
