Guild Wars 2

The following three events are not spawning.
“Defeat the grawl commander” in Timberline Falls.
“Assault Foulbear Kraal by killing its leaders before the ogres can rally” in Fields of Ruin
Event chain stalls at Bloodforge Camp even when Camp and Sapper’s Delve are both held.
“Toil for the Coil” in Mount Maelstrom

EDIT I got the Toil for the Coil completed after three days of checking in on this event (and at the moment I am unemployed and playing a lot).
