Talking in the discord, a bunch of the developers think exceptions are normal. They think we should silently hide them and just accept that errors happen.
I disagree with this. If an unhandled exception happens then you fucked up. If we ignore it, it could propagate and cause more errors. It could stop your game from working. It's a shitty experience for end users.
In an attempt to solve this I wrote a whole exception reporting system, so you can go into your organisation or game, and see all the errors reported. Then you can fix them. And then you have no more errors.
We felt it was unfair to do it without warning, but at some point in the future we'll make it so when a player gets an error in a game they're immediately disconnected from that game.
