Guild Wars 2

I cannot see the boss event description at top right corner now

1) I am now sure that the world boss is dead or alive when i am late
2) I cannot right click to the boss health directly from the event showing on the right. It is hard to click on the boss if i turn off the auto targeting.

I have same problem since expansion update. But not only for bosses, but also for regular events. Half of them show, half not. No orange circle on minimap, no event description in the top right panel. Just like there is no event at all. And for some of the bugged invisible events I get contribution, for some not

Description disappear when step few forward
Description appear in a small area only

I’ve also experienced this near frozen maw
