If you use this troop Lord Harker, to gain an extra turn from it’s conversion of brown gems to bleeding gems, it will not happen like this pic would obviously get you one from the 5 match in the upper left corner of the board.
It only gives an extra turn if it makes a 4 or more match from the explosion only.
If this is intentional then it’s the first troop ever to make a 4 or more match and the game doesn’t grant you an extra turn during any part of a spell but this one.
If it works properly in the pic above I should of gotten an extra turn from the 5 match but I don’t. The graphic doesn’t show this at all happened I.e. extra turn bubble popping up, only when the second mechanic happens during the explosion part, so I believe the troop is bugged.
I’m using an ANDROID V13 on a Samsung tablet. And it happens everywhere all the time.
