Duplicate cards can be traded again

I just uploaded bugfix release 1.3.1 to Google Play, including the following fixes: - Duplicate cards can be traded again - The currently equipped item is not transmuted when double tapping - Stats depending on level are calculated correctly after replacing tower - Aura of Unlucky Pants is still effective after replacing the carrier There are a few reported issues I could not reproduce so far. I'm still trying, but probably need more information and time. I noticed the trade duplicate issue was bugging a lot of you, so I decided to ship a bugfix update with what I have so far. Happy building (& trading duplicates)! PS: iOS 1.3.0 still in Apple review!.
