It is really easy for us to say that not everyone is bashing the game. but from Flynns perspective, you are about to release an update, you are probably proud of how it turned out, you are nervous about how it will be received, it gets leaked on here, and suddenly the forum is suddenly inundated with people who do one sentence "update bad" posts. So even though there were some few who had valid criticisms and presented them in a not shitty way, they are often drowned out in the sea of "drive by" forum members who only show up when a new update comes out, who feel the need to shout their opinions at whoever is unfortunate enough to be near them.
If I was Flynn I would make an effort to keep F95 closed for like 2-3 weeks after the update gets leaked, these forums often get really toxic after a game updates, and this one especially felt really overwhelmingly vitriolic. I would hate to see Flynn stop coming here, but I would understand it.
