In-game bug categories are insufficient
Regardless of how we categorize it, the first tier person looking at the report is almost certainly going to reclassify it in any case — the main purpose of categorization is to assign it to the relevant QA team and those tend to evolve over time.
When I’m reasonably sure that the categories don’t apply, I add a note at the top and choose something generic from the pull downs.
It would be good if there was a “General: Other” or “General: None of Above” option, but I’m not sure how much time it would save anyone, including the players.
