ADD A SAVE FEATURE AND STOP HAVING BUGS WIPE OUT 30-60 MINUTES OF PROGESS
Several times during co-op we've completed all objectives and it will not progress. I was on [WINDOWS 11 PC]
I was using Quick Play Co-Op
I was playing as Cati with a Drizzt
No work around, tried suicide to respawn last room (Cultists to stop on Act 2 of Crystalline Dreams 'Act II: Crystal Harvest'), tried killing/exploring whole map
Similar incident happened last week with co-op while we played an Act 3 where you gather wisps to revive the forest spirit but after killing all side-bosses and gathering wisps... nothing. (Act III of The Crystal Wraiths - Seven Masters)
Of course with the wonderful save system in mid-mission I totally didn't lose over an hour of progression with my 2nd character including a legendary ring and a whole maps worth of gold/lore/items....
