We've just posted an update that fixes a few small bugs and inconsistencies, including the stat page timer not showing hours and achievements being unreliable.
- FIX: Timer on the stat page now reads Hours:Minutes:Seconds instead of just Minutes:Seconds when the player exceeds 60 minutes played
- FIX: Creds now always properly count towards unlocking achievements.
- FIX: Achievements for buying upgrades now reliably unlock as intended
