To my understanding, these new crown store upgrades give you 10 bag/bank slots for one flat price, no matter how many slots you currently have. However, as we all know, the gold cost of upgrades increases each time you increase you bank/bag slots (not including horse carrying space upgrades). So I would like to know if purchasing these crown upgrades also increases the gold cost of an upgrade, or if the gold cost will remain the same even after increasing bank/bag space via the crown store.
In case my question is unclear, let me provide an example. For the sake of simplicity, let's just say the first bank upgrade costs 1000 gold, and the second costs 5000 gold. Obviously after purchasing the first upgrade with gold, the price for the second upgrade will be 5000 gold. However, if I purchase the first upgrade in the crown store, would the next upgrade still cost 5000 gold, or will it only cost 1000 gold since the first upgrade was purchased in the crown store and NOT with gold?
This is an important distinction, because if the former is the case, these crown store purchases become much less valuable the fewer slots you already have purchased with gold.
(Also, I apologize if this is worded poorly, I just got home from a music festival 6+ hours away so I am extremely exhausted and my cognitive functioning is pretty poor at the moment.)
