Do you test Heart of Gold Expansion before sell it?

At first map.

1) Most of the picked artifacts disappear (imp bring artifact in room, and artifact disapear ...)

2) I capture prison right at invulnerable gates, but cant pick up prisoners from it.

3) When i use FPS mode on stuttering mage,camera stick at top, and i cant cancel it (and i cant open menu).

Played one time first map and find 3 bugs, then how many bugs total?
