Release Spirit

My corpse keeps laying there in Battlegrounds. Why? The “release spirit” button becomes grayed out. All Battelgrounds so far that I have entered.

This was happening to me multiple times tonight.
I tried every suggestion I’ve seen (reload, relog, a repopMe script Blizzard suggested on an old thread about this, the stuck character option in the help menu), nothing helped.
This has apparently been going on for some time, it needs to be fixed (of course) but it should really at least be in the known issues thread at this point.
