Sometimes the game doesn’t realize you’ve done more simulating. Go to your settings page and toggle the sound option. Each time you change it, it has a chance to re-check the achievements.
Right, simulating games will only update your achievement every once in a while (10% of the time you save your user object, maybe by beating a level or changing a setting or something). Otherwise you’d constantly be seeing the simulation achievement pop up. So if you really want to refresh your gems from simulating, play some more levels or twiddle your CodeCombat volume a bunch of times.
I can’t remember how many simulated games it takes to earn more gems, so you might have to do a bit more to get the gems you ned.
The Emperor’s Gloves is one of my favorite items.
We don’t have a way to reset just one purchase – the only reset we have is a full reset, which starts you over completely.
