Multiple Debuffs Inflict Permanent Slow on Character after Expiring (Video)

This has been an issue since Dawn of the Hunt.

What happens is if your character has 1 or more slowing debuffs applied to them in a short period of time, after the debuffs expire, the character still has slower Action Speed. Casting, Attacking, Running, Animations, and Portalling all seem to be affected.

I've had this happen as early as Act 1 and also in Maps across multiple classes. I don't believe it is isolated to a single type of Debuff, but instead anytime multiple Debuffs are applied that affect Action/Cast/Movement Speed.

The only way I've been able to get rid of the slowness is by portaling to Town, which appears to reset the Action speed of the character.
