Many different things triggering twice sometimes [Fix in 2.9]

Seen this quite a bit will give some e.g. if a treasure gets triggered sometimes it only triggers the mana once sometimes it’s two times, some supports at beginning of turns trigger twice other turns it’s the normal one, and another is Koth ult whenever someone matches red sometimes it gets triggered twice so creatures get 8/8 but again it’s fine other red matches so a strange old bug where stuff happens twice idk how to be more specific with this anyone else seen this with some cards. Also Haggar Walker sometimes gives you 2 thopters even with a single 3 match many cards seem to have this problem.
