Not sure if this is the place to identify issues. If not please let me know where.
I've noticed that Merisiel (with the LT Armor ability) cannot recharge armor "Locksmith Leather".
On my Android tablet I've found that I have to close the Pathfinder app, and then refresh my Google Play account and then open the Pathfinder app to get the "Store" to show that I have gold to acquire (I purchased the 30 day option).
