that is very sad. I would not have thought that Isaac would react in that way. Communication on the Frosthaven updates did not sound like that.
Gloomhaven helper was a high quality product and improved playability by a lot. Esoteric games did Cephalofair a great service. Sad to see it end this way.
It's only one side of the discussion represented here. There are some more impeachments on both sides. All in all, from all I know it seemed just like really bad communication in both sides.
Some say, it was also a bad move to just remove GHH, it could have stay online for free or released as OSS. I am not here to judge, I just hope my Gloomhaven Secretary will be a good successor. We used this app too. Now I can easily add my own improvements ideas and also make some community members happy with implementing their feedback by developing my own app.
