I died in the cannon event on Fort Brokenback near the high balcony cannonball spawn spot, but when I respawned I was placed in the previous area.
When I died I was a Saltspyre’s length away from the wall facing the drop off point from the previous area, and died to a chaos warrior that had been up there since before the event began, one that had noticed me before I dropped down, if that helps. A teammate also died after I did, but he respawned in the event area as he should.
I’ve also had a similar experience happen in Skittergate with myself and a teammate, but I saw someone already reported that.
