MVPs are just other players so it does not mean Devs don’t know. QA covers this forum so i assume they have read those posts.
Something that is an issue for troubleshooting in Diablo games - there is no second by second log showing what happens to items, no combat log, etc. It just snapshot saves the account. There is nothing for the Devs to trace to try and verify reports.
They have to try to replicate it in house then sort it out.
I have not run into it yet, but will keep an eye out.
