gems stopped increasing

[mammaduck]

Has anyone else had any issues with gems? I used to get a gem each time I completed a stage if each clothing item but recently I've not got any

You only get gems when you master level 2 and 4 of a catalog.

Once you reach. Lvl 4 on each item in a catalog you no longer receive gems. Gems are rewarded at lvl2 and 4 for each item once you reach lvl4 that catalog or item is considered mastered. You will continue to receive experience points after reaching lvl4 if you continue to order more of those items.
