when it fires, one of the countdown tiles is randomly incrementing faster than the others. So I’ll have three spawn, but one will show up with a 2-turn countdown instead of a 3-turn countdown, while the other two have a 3-turn countdown, and they end up proc’ing on two separate turns.
This can happen if the match-5 was created by a countdown, because of the way countdowns resolve (top left to right down). If, during the countdown resolving sequence, a match occurs that causes other countdown tiles to drop down to the ‘unresolved’ part of the board, it will still receive a countdown even if it was just placed.
I would still call it a bug tho
