I have heard that FDEV applies a threshold based on how many contributors can reproduce issues posted in the tracker, in the 10-15 person range. Without more aggressive moderation to combine related issues, this means most people's issues silently pass from confirming to closed despite other people having reported the same issue separately. This undermines people's willingness to use the issue tracker.
E.g., issues with the Odyssey pre-order Pioneer suit cosmetic. I'm finding lots of individual reports, phrased a bit differently but all having the same of two problems: they don't see Pioneer as an option at all, and the Pioneer pieces don't show in the selection UI after being selected.
FDEV, you need to come up with a way (manual or otherwise) to more actively link and combine related issues in a much more timely fashion so it's apparent how many people are actually experiencing the same problem so those issues get properly prioritized and fixed.
