I’m not sure how if your game ‘crashed’ and your app closes and it returns you to your last saved position that can remotely considered in the gaming world an exploit. That’s a feature of the game so people don’t get angry about losing progress. The whole point of a saved game since the invention of gaming is so you can have a do-over. For Warriors of Waterdeep that safe position is a very small one and were it completely unacceptable the programmers wouldn’t have it coded into the game.
An actual exploit on a game is more like an illegal mod like using an aimbot within a first person shooter or hacking a game’s vulnerability to get free gems or something.
Telling someone how to get past a part of the game that is IMPOSSIBLE to get past due to an issue with in game mechanics (a quirk in this case - as the fire would have settled the match in a similar PvP scenario) is being HELPFUL in this situation and not in the least bit exploitative.
Compare this with the 2 members of Ludia who have looked in on this issue and been thoroughly UNHELPFUL. One squelched the solution and another waded in to back them up. Neither came up with a helpful suggestion or even offered to pass on the issue to the dev team.
And you wonder why people are becoming increasingly alienated by and frustrated with this game?
