Earlier today, I triggered a trapped chest that caused a Blind effect on 4 of my 6 party members. No big deal at the time, however after multiple hours of gameplay (including many rests/camps, area transitions, etc), those 4 characters still show a Blind status effect symbol. I am not sure if they are experiencing any effects from it, but would like to know if there is a way to make it go away...
Here's a link to the 4 characters' portraits and the Blind symbols. Notice how the symbols are above the ones for resting at an inn and the Fighter's Defender buff because they've been present longer.

So yeah, I'd like it to go away. If that's not possible, is there a way to, definitively, tell if it's actually causing a debuff?
