There is a Know Issue regarding Emblems going in negative, and/or talent grid not progressing as it should.
We are currently investigating this issue and expect to have it fixed as soon as possible.
Thank you for your patience and our apologies for the inconvenience caused by this!
EDIT (Jan 14): We believe we have isolated the issue. It seems to be only affecting Android users and can be solved by restarting the game. The Emblem count should return to normal after restarting. We will be releasing a new build to fix this issue as soon as possible.
EDIT (Jan 15): We have deployed a fix, if you have not yet, please make sure you are running the newest Build (884).
