I’m reporting several bugs — just so you know, it’s not to complain, just to help! 😉 In the Achievements, “Gallery completed” is always marked as achieved from the start.
Being Canadian, I thought maybe you speak French ? If you do, I can report bugs in French from now on (it's my first language). If not, no worries, I'll keep going in English ;) (I assumed you are Canadian because you said 10CAD in an old post).
