What is difference between bug reported from in-game dialogue and submitted through forum web page?
The bug report in-game will collect data from the current game state to help devs pinpoint what’s going on.
Oh, and you don’t get replies to the in-game report but you get replies from other players (and presumably the devs sometimes) here.
One thing I find tricky is reporting any bug related to enemies. As either you or the enemy will die before you submit it with screenshot.
If you find a bug with it you can always report anyway, just describing what happened. If it’s a bug, a verbal description is better than nothing.
