Guild Wars 2

when I pop my symbol of swiftness + retreat + save yourselves I have 48 seconds of speed every 48 seconds, so perma speed.
However just recently I’ve noticed that my swiftness buff completely goes away with just over 15 seconds remaining on it. anyone else having this happen?

and then around 18 seconds it starts blinking like it’s fading then poof, it’s gone at around 15 seconds remaining

It is the Symbol of Swiftness. Retreat and SY work properly and stack properly with full boon duration gear I can get over 1 min of swiftness. However whenever Symbol of Swiftness adds duration as soon as its duration is gone all stacks of swiftness are removed. Get around this by using symbol only when you don’t have any swiftness on you and wait till it falls off to use Retreat and SY
