The only way I know of would be to contact Support and ask for a transcript for say 3 days. I do not know if they can but they are the only people with the capability. https://plariumsupport.zendesk.com/hc/en-us/requests/new

Is there a way to check what you have spent soulstones on recently?  I seem to be missing a bunch, and dont recall spending them...

There support team can help you with that.

It will be a tedious job to calculate how much you've earned. But you can try that. You'll need to know how many you earn per leveling up your castle and how many have you earned through tournament, and league achievements.
