Guild Wars 2

This is an everlasting problem. Today it happened twice in a 2hour(or less) farming time. I start event damage boss, steady high damage output during event, have boss locked on target, hitting boss, boss dies . no chest. but others can loot. Was in party and all other party members could loot chest but me, what gives? WHERE’S MAH LOOT! >:( (other times in past solo’d event and same thing happens)

Please ingame mail me my precursor that would have dropped those times that chest didn’t spawn. Thank you.
