Doctor Octopus "Insult to Injury" triggers on unmatched special tiles destroyed by a match-4
This feels like a regression compared to previous behaviour, but I obviously have no way to compare with old versions of the game.
From a reading of Doctor Octopus's black power, he should only create attack tiles when an enemy special tile is part of a match. When a player makes a match-4 or match-5 to clear a line, my understanding was that only the tiles that were part of the match-4 counted as "matched", with the other tiles simply being "destroyed". So I would only expect the power to fire if a special tile was part of the match.
In the recent Doctor Octopus PVP event, I have noticed multiple occasions when a match-4 cleared a line containing a special tile (but wasn't one of the matched tiles) and attack tiles were still created. This happened both for my team and the AI enemy team.
