Today we pushed some changes that no longer require logging in with a password to your Faeria account. This change is meant to prepare us for future console releases.
In consequence of this patch we’ve had a few issues emerge where players are reporting the inability to craft cards or open chests.
Will be issuing a hotfix for these issues tomorrow - but for now you may be able to workaround these problems by restarting the client entirely.
Sorry, and thank you for the inconvenience! Wait… the other way around…
