Sunder Mind Difficulties

[BoardroomHero]

I posted this in the Solipsist forum, but I'm cross posting here because it's also a dumb question.

Is there a problem/bug with Sunder Mind right now? I remember it used to have a long enough duration to easily re-apply, but recently I have been having significant difficulties recasting before the debuff goes away. It feels as if the debuff duration was reduced from 4.5 turns, or something like that, to exactly 4.0, which makes it disappear if you have a global speed higher than 100%.

Did something change?

Could be that the target's mind save is reducing the duration.
