We run our KS in GBP which means that no matter what currency you pay in we get the money from KS in GBP. All prices in PM are therefore calculated around GBP. First of all – don’t worry, everything that you have paid during the Kickstarter will be in the exact same exchange rate as during the Kickstarter. (you are receiving exact amount of credits). After the Kickstarter exchange rates of USD / GBP changed and the prices in the Pledge Manager reflect that change (in Kickstarter the USD costs were estimations based on the currency exchange rate).
