* game: now all playable calculations done in game simulation, outside real game (no more freeze and ruined games by wrong Nyxbloom Ancient and other cards with wrong replacement dialog); * game: fixed multiple problems with triggers (wrong order, duplicated calls or "too many mana" bugs, see #8426, #12087); * tests: added data integrity checks for game's triggers (3 enabled and 3 disabled due current game engine logic);
