The See invisibility spell from Gale doesn't seem to work very well. I 've taken the habit of casting it on Gale after leaving camp, as it stays active until next long rest, so I'm always prepared.
I also have its glowing icon over Gale's head and next to his avatar, so the spell is active.
Yet when foes become invisible/shrouded, Gale can't see them either. Is this a bug ? Or am I missing something.
